6 04-jul-1997 NvE First release of the package
7 11-jul-1997 NvE Class Invmass added to /GENUTILS and directories /PHYSICS
8 and /TRACKING created to hold Jet and Track classes resp.
9 15-aug-1997 NvE Pilot patch *RALICE removed and automatic installation
10 now completely performed by pure CMZ commands in the
12 12-sep-1997 NvE Signal of central cluster module and position in user
13 coordinates for all modules introduced in the Calorimetry
15 Also all "float vec[]" replaced by "float* vec" in the
16 Lorbo class for stylistic reasons.
17 20-sep-1997 NvE Name of member function "getc()" of Calorimeter changed to
18 "get_c()" to avoid clash with native C function.
19 Also protection added in Calorimeter::group() against cases
20 where no modules fired.
21 23-sep-1997 NvE Macro "install" modified to also enable automatic installation
22 of a G++ or ROOT loadable shared library 'ralice.sl'.
23 24-sep-1997 NvE Class "Calorimeter" optimized by introduction of pointers
24 for the Module matrix instead of an indexed array.
25 26-sep-1997 NvE Directory /ROOT added to hold the universal ROOT dictionaries
26 (dict.h and dict.cc) as generated by "rootcint" for all the
27 classes of this RALICE package.
28 This will allow automatic installation of the RALICE library
29 without running "rootcint".
30 30-sep-1997 NvE 2-body decay added to class Track and invokation of "delete []"
31 only performed in case the object exists in the destructors
32 of the Calorimeter, Jet and Track classes.
33 02-oct-1997 NvE Installation for MSVC++ added into macro "install" and several
34 "return 0.;" statements added in some "Sample" member functions.
35 The latter caused MSVC++ compiler errors.
36 Also 'int ..=fabs(int..)' changed to 'int ..=int(fabs(int..))'
37 in "Cluster::Add()" to prevent G++ warning.
38 03-oct-1997 NvE The above code is now ANSI compatible, but MSVC++ 5.0 still
39 gives an error when comp. extensions are switched off (flag /Za).
40 The reason is probably an incorrect implementation of the ANSI
41 type conversion rules in MSVC++. To satisfy MSVC++ for the moment
42 the code in in "Cluster::Add()" has been changed to
43 'int ..=int(fabs(double(int..)))' so that at least a Microsoft
44 compatible RALICE.DLL can be produced. As soon as G++ is able
45 to produce Microsoft compatible dll's the support for MSVC++
46 will be dropped for ralice.cmz.
47 Message to all : USE G++ AS COMPILATION STANDARD !
48 Also CMZ standard adopted to include a "$" in the DECK names
49 which contain KEEP definitions.
50 13-oct-1997 NvE Compiler directive for g++ changed in "flogon" and "install"
51 to provide warning for each non-ANSI C++ statement.
52 Also ROOT libs linked with g++ in "install" in case of
53 ROOT loadable shared library creation.
54 Unused variables removed in "Calorimeter::add_ring" and
56 14-oct-1997 NvE Strict ANSI requirements dropped for ROOT loadable lib creation
57 to avoid many harmless warnings from rootcint generated code.
58 Class "Random" added to /GENUTILS and /ROOT updated accordingly.
59 14-oct-1997 NvE Class "Random" extended with user definable distribution and
60 /ROOT updated accordingly.
61 19-oct-1997 NvE Class "Random" extended with vector facility for user
62 defined dist. and also bug fixed. /ROOT updated accordingly.

69 23-mar-1998 NvE Macro "install" modified to support HP-CC.
70 Multiple usage of for-loop index names removed to satisfy HP-CC
71 compiler (although the original code was ANSI C++).
72 Cluster data just reset to 'empty cluster' in case of cluster
73 'creation' or 'start' for edge module or no-signal module.
74 31-mar-1998 NvE Array index bug fixed in class Jet.
75 03-apr-1998 NvE Jet and Invmass classes optimised by using pointers and
76 compiler options /GD and /DWIN32 introduced for msvc++
77 in order to optimize for windows DLL's and ensure correct
78 pre-processing in RConfig.h for ROOT library creation.
79 13-apr-1998 NvE ROOTCINT processing implemented in $KUMACS/INSTALL and
80 contents of /ROOT updated accordingly.
81 Class Vertex added to /TRACKING and classes Track and Jet
82 protected against modifying of returned addresses.
83 14-apr-1998 NvE "rm .def" removed for Unix systems in $KUMACS/INSTALL since
84 on Unix no .def file is created by ROOTCINT.
85 17-apr-1998 NvE Return type Track& changed to Track* in the get_trk()
86 member functions of the Jet and Vertex classes.
87 21-apr-1998 NvE Classes Track, Vertex, Jet, Lorbo and Invmass derived from

99 DOC section updated for new email and www address.
100 17-aug-1998 NvE New ALICE coding conventions adopted and automatic marking
101 of 'edge modules' introduced in class AliCalorimeter.
102 The automatic treatment of edge modules required new member-
103 functions EdgeUp() and EdgeDown() in class AliModule.
104 19-aug-1998 NvE Call to LoadMatrix() added in AliCalorimeter::Group()
105 to correctly treat different event sizes (i.e. empty events)
106 when reading data from input file(s).
107 25-aug-1998 NvE AliCalorimeter::GetModule() introduced to provide quick
108 access to all 'fired' modules.
109 27-aug-1998 NvE GetSignal() and GetClusteredSignal() of AliModule now
110 return 0 in case the module was marked as dead.
111 Because of the above, protection against row=col=0
112 introduced in AliCalorimeter::Group().
113 To enable access of modified calorimeter module data via
114 AliCalorimeter::GetModule() after reading in, the "fModules"
115 elements are updated in AliCalorimeter::LoadMatrix().
116 16-sep-1998 NvE Correct deletion of the module matrix introduced in the
117 AliCalorimeter destructor and AliCalorimeter::LoadMatrix().
118 16-oct-1998 NvE New ALICE coding conventions adopted. This resulted in

130 26-oct-1998 NvE DrawModules() and DrawClusters() histogram axes defined such
131 that the X and Y axis corresponds to columns and rows resp.
132 in AliCalorimeter. This view matches the 'common sense'.
133 06-nov-1998 NvE SetDirectory(0) invoked for the histos created in
134 DrawModules() and DrawClusters() to suppress global character
135 of the histo pointer.

186 24-sep-1999 NvE In Ali4Vector internally the Lorentz invariant (x^mu x_mu) is now stored
187 instead of the scalar part x^0. This will yield better precision and
188 e.g. automatically conserves the particle identity (mass) in elastic
190 08-oct-1999 NvE GetResultError() introduced in Ali3Vector to provide error information
191 on results obtained from operations which yield a scalar.

244 because of problems with I/O in ROOT 3.00/06 w.r.t. multiple inheritance.
245 29-may-2001 NvE Position reset added in AliVertex::Reset().
246 01-jun-2001 NvE Memberfunctions Add() renamed explicitly to AddTrack(), AddJet() and

339 script for Linux machines using gcc.
340 Class AliObjMatrix introduced.
341 08-feb-2003 NvE Class AliSignal modified such that the maximum number of signal slots is
342 handled completely dynamically at runtime.
343 Memberfunctions SetSignal() and AddSignal() of class AliCalmodule declared
344 virtual to enable inheritance.
345 09-feb-2003 NvE Class AliCalcluster derived from AliSignal to enable automatic signal setting
346 for various rings of modules around the cluster center.
347 10-feb-2003 NvE Class AliSignal modified such that also signals without errors can be stored.
348 This may minimise memory occupation and output file size.
349 18-feb-2003 NvE Memberfunction ShowCalorimeters() introduced in AliEvent to display an overview of all
350 available calorimeter systems.
351 Date/time format changed and ShowCalorimeters() invoked in AliEvent::HeaderData().
352 08-mar-2003 NvE Compiler option /GR introduced for MSVC++ in mklibs.bat to explicitly enable
353 the C++ RTTI. This prevents a warning when creating shared libraries
354 using the "old streamer method" (i.e. NO "+" behind the class names
355 in the Linkdef file).
356 10-mar-2003 NvE AliPosition datamembers of AliTrack changed into AliPositionObj* to enable
357 minimisation of memory occupation and output file size in case a track
358 has not all attributes set.

362 ANSI compliant compiler problems.
363 15-apr-2003 NvE Waveform histogram introduced in AliSignal.
364 29-apr-2003 NvE Memberfunction MakeCopy introduced for AliSignal and AliCalmodule.
365 This memberfunction enables automatic creation of new objects of the
366 correct type depending on the argument type, a feature which may be very useful
367 for containers like AliCalorimeter when adding objects in case the
368 container owns the objects. This feature allows e.g. AliCalorimeter
369 to store either AliCalmodule objects or objects derived from AliCalmodule,
370 provided these derived classes also have a proper MakeCopy memberfunction.
371 17-jun-2003 NvE All TString objects "s" replaced by "s.Data()" in cout statements to comply
372 with MSVC++7.NET compiler and allow mixing with MSVC++6 libraries.
373 The classes in which these modifications were made are Ali3Vector, Ali4Vector,
374 AliSignal and AliEvent.
375 20-jun-2003 NvE Copy constructor introduced for nearly all classes and also all destructors
376 explicitly declared virtual.
377 11-jul-2003 NvE Functionality of AliObjMatrix extended by enabling removal of objects and
378 introduction of a linear object array for fast looping over the stored objects.
379 15-aug-2003 NvE Usage of TMCParticle removed from AliCollider; only Pythia intrinsic functionality
381 01-sep-2003 NvE Explicit initialisation of TObject() introduced in default constructor of AliObjMatrix.
382 16-sep-2003 NvE Parent track pointer introduced for AliTrack.
383 Functionality of AliSignal extended and support for gains and offsets introduced.
384 Gain datamember removed from AliCalmodule.
385 17-sep-2003 NvE Memberfunction AddTrack with second argument "copy" of AliJet moved into the
386 "protected" area to avoid confusion among users.
387 The user has now only access to the AddTrack memberfunction with only the track
388 (pointer) as argument.
389 23-sep-2003 NvE New classes AliAttrib and AliAttribObj introduced to centralise the handling of
390 name, gain, offset, edge and dead value attributes for a certain slot.
391 Classes AliSignal and AliCalmodule updated accordingly.
392 28-sep-2003 NvE Facility for automatic gain etc... correction introduced in AliSignal::GetSignal().
393 30-sep-2003 NvE New version of AliCalorimeter introduced, making use of AliObjMatrix and AliAttribObj
394 and supporting full treatment of module gains, offsets etc...
395 Also class AliCalcluster updated to take gain etc... correction into account.
396 02-oct-2003 NvE Memberfunction Load() moved from Ali3VectorObj and Ali4VectorObj to Ali3Vector
397 and Ali4Vector respectively. This allows to use this memberfunction also in
398 all the derived classes (e.g. AliPosition, AliSignal, AliTrack, etc...).
399 Therefore the Load() memberfunction has been removed from AliPositionObj.
400 03-oct-2003 NvE Typos fixed in AliCalorimeter.cxx.
401 Also memberfunction MakeCopy introduced in class AliCalorimeter.
402 07-oct-2003 NvE Arguments of SetSignal and AddSignal memberfunctions of AliCalmodule corrected
403 to comply with the corresponding virtual functions of AliSignal.
404 AliCalorimeter modified accordingly.
405 09-oct-2003 NvE Argument of all MakeCopy memberfunctions removed to obey the ANSI C++ rules for
406 virtual functions and to prepare for a common base class.
407 Due to the fact that not all compilers seem to accept the standard ANSI rule
408 that a virtual function is allowed to differ in return type from the corresponding
409 virtual function in the base class, the MakeCopy() memberfunctions have all been
410 given a return type of TObject*.
411 Also AliAttrib::Data renamed to AliAttrib::List to prevent violation of ANSI virtual
412 function rules and class AliSignal updated accordingly.
413 Memberfunction ResetPosition() moved from AliSignal to AliPosition.
414 Explicitly declared all memberfunctions virtual in the derived classes in case
415 the corresponding memberfunctions were also declared virtual in the base class.
416 Various memberfunctions which were declared virtual but were actually not meant
417 to be overridden declared as non-virtual in various low-level classes like
418 Ali3Vector, Ali4Vector, AliPosition etc...
419 13-oct-2003 NvE Argument 'npt' of AliCollider::MakeEvent also made optional.
420 24-oct-2003 NvE Private memberfunction Dump of AliTrack and AliVertex renamed to Dumps in order
421 not to override the Dump memberfunction of TObject.
422 Also definition of AliVertex::Draw slightly modified to comply with the standard
423 ANSI virtual function rules concerning TObject::Draw.
424 Invokation of ClassName() used in printout of AliSignal::Data to make the output
425 information more generic.
426 25-oct-2003 NvE Memberfunction AddCalorimeter of AliEvent replaced by memberfunction AddDevice
427 to make the functionality more generic.
428 To comply with the enhanced flexibility of AliEvent::AddDevice the class
429 AliCalorimeter has been derived from TNamed and the MakeCopy() memberfunction
430 has been replaced by Clone() to override the default one of TNamed.
431 The specific GetName and SetName memberfunctions of AliCalorimeter have been removed.
432 26-oct-2003 NvE Class AliSignal derived from TNamed and MakeCopy() memberfunction replaced by Clone()
433 like was done for AliCalorimeter.
434 The latter was also done for AliCalmodule and AliAttribObj.
435 29-oct-2003 NvE Obsolete include of AliCalorimeter.h removed from AliEvent header file.
436 11-nov-2003 NvE Double_t dum=GetScalar() replaced by e[0]=GetScalar() in Ali4Vector.cxx to prevent
437 a warning for the gcc compiler (thanks to Thomas Burgess).
438 AliJet derived from TNamed instead of TObject to allow identification via name.
439 12-nov-2003 NvE fDaytime datamember of AliEvent changed from TDatime to TTimeStamp in order to
440 obtain nanosecond precision. Setting of date and time via a TDatime argument is
441 still supported to provide backward compatibility.
442 13-nov-2003 NvE Invokation of AliAttrib memberfunction Data() replaced by List() in the example
443 in AliAttrib.cxx (was just a typo; thanks Adam Bouchta).
444 Also test on pointer value introduced in AliAttrib::GetSlotIndex to prevent
445 crash when first slot is empty (thanks to Adam Bouchta).
446 21-nov-2003 NvE Variable names of type "const" started with the character "k" in various
447 memberfunctions of AliMath in order to comply with the strict Alice
449 22-nov-2003 NvE Support for various computation modes introduced in AliMath::Prob.
450 23-nov-2003 NvE New memberfunctions GetBetaVector(), GetBeta() and GetGamma() introduced in Ali4Vector.
451 03-dec-2003 NvE Message removed from AliEvent::GetDevice in case there are no devices present.
452 05-dec-2003 NvE Memberfunction SetStable introduced in AliCollider for the user's convenience.
453 08-dec-2003 NvE AliTrack derived from TNamed to enhance labeling flexibility and also specific
454 Clone memberfunction introduced to enable storage of derived objects in AliJet & co.
455 Also specific Clone memberfunctions introduced for AliJet, AliVertex and AliEvent and
456 for the already existing specific Clone memberfunctions the default argument was set
457 to the empty string "".
458 15-dec-2003 NvE Datamembers fNdec and fNsig removed from AliTrack since these data are now retrieved
459 directly from the corresponding arrays.
460 Support for hypothesis probability introduced in AliTrack and old mass hypothesis
461 machinery extended to provide now full track hypotheses.
462 18-dec-2003 NvE Support for object references from the various signal slots introduced in AliSignal.
463 Since this is mainly intended for "backward references" to AliTrack objects,
464 the AliTrack class has been slightly updated for this to provide pointer consistency
465 in case the corresponding AliTrack object is deleted.
466 19-dec-2003 NvE Slight modification in AliVertex.h and AliAttribObj.cxx to prevent gcc compiler
467 warning concerning an unused variable.
468 22-dec-2003 NvE Event selection introduced in AliCollider.
469 24-dec-2003 NvE Some cosmetics in printout of AliVertex, AliEvent and AliCollider.
470 Support for spectator tracks introduced in AliCollider.
471 28-dec-2003 NvE Facility introduced in AliCollider to set minimal momentum for spectator tracks
473 06-feb-2004 NvE "char* name" changed to "const char* name" in all specific Clone memberfunctions
474 to prevent compiler warnings on Sun.
475 Memberfunction Set() of TTimeStamp used in AliEvent instead of setting the date/time
476 via the TTimeStamp constructor. This is only possible with ROOT version 3.10/02 or later,
477 since for earlier versions the TTimeStamp::Set memberfunctions were erroneously declared
479 11-feb-2004 NvE In script "gcclib" the option -Wno-long-long added to prevent warnings from the usage
480 of type "long long" in Rtypes.h
481 12-feb-2004 NvE In AliCollider::MakeEvent the statement "char* name" was replaced by "char name[16]" to
482 comply with TPythia6 convention. Also the hardcoded values of the p and n masses have
483 been replaced by masses obtained from the Pythia system via a call to GetPMAS().
484 Because of a bug in TPythia6 the function Pymass() couldn't be used directly.
485 13-feb-2004 NvE AliCollider::GetPyname introduced to provide a correctly stripped character string
486 for the particle names. The name returned by TPythia6::Pyname contains trailing
487 characters due to an incorrect stripping process.
488 AliCollider::MakeEvent was updated accordingly to make use of this new memberfunction.
489 04-mar-2004 NvE Functionality of AliObjMatrix extended to provide the number of references and
490 (row,col) indices of all the occurrences of the stored objects.
491 Also an additional memberfunction AliObjMatrix::RemoveObject introduced to allow more
492 flexibility in specifying objects to be removed.
493 09-mar-2004 NvE Additional memberfunction AliObjMatrix::RemoveObject renamed to RemoveObjects to prevent
494 confusion and ambiguity in usage.
495 Linking facility of AliSignal extended by enabling multiple links to a specific signal slot.
496 Also call to AliSignal::ResetLink changed to AliSignal::ResetLinks() in the dtor
497 of AliTrack to adopt the extended AliSignal linking facility and output in
498 AliTrack::ListAll() limited to only the referring signal slots to prevent long output lists.
499 12-mar-2004 NvE Additional "cout << endl;" in front of AliCollider initialisation message in order to always
500 have the initialisation message starting on a new line. On some systems the fortran
501 carriage control of the pure Pythia doesn't get treated correctly.
502 04-apr-2004 NvE SetMass() invoked from AliTrack::Set3Momentum to get also the energy properly initialised.
503 09-apr-2004 NvE Support for specification of unit scale introduced in AliPosition.
504 19-apr-2004 NvE Memberfunction GetPrimed introduced for Ali3Vector.
505 04-may-2004 NvE Various memberfunctions declared "const" to satisfy the strict Alice coding rules
506 and also to allow better compiler optimisation.
507 12-may-2004 NvE Track reference-point introduced in AliTrack.
508 02-jun-2004 NvE Memberfunction GetUnprimed introduced for Ali3Vector.
509 17-jun-2004 NvE New class AliHelix introduced and "macgcclib" added to create ralice libs on MAC.
510 24-jun-2004 NvE Coefficient kp7 changed from 7.4e-5 to 7.4e-6 in AliMath::BesselK0 to correct typo
511 (thanks Josh de Bever).
512 Typos corrected (i.e. abs() replaced by fabs() in several places) in AliHelix
513 to satisfy the Intel compiler (thanks Fons Rademakers).
514 25-jun-2004 NvE Protection introduced in AliSignal::GetNlinks.
515 29-jun-2004 NvE New class AliDevice introduced.
516 New memberfunctions and datamembers introduced in AliEvent to support investigation
517 and ordering of hits of various (classes of) devices.
518 01-jul-2004 NvE AliCalorimeter derived from AliDevice to extend functionality (e.g. allow definition
519 of sets of calorimeters and investigate all the hits of a certain set via the
520 AliEvent structure). To prevent matrix swapping restrictions, the memberfuctions
521 SetSwapMode and GetSwapMode of AliCalorimeter have been renamed to SetMatrixSwapMode
522 and GetMatrixSwapMode, respectively.
523 Examples in the AliEvent.cxx documentation updated accordingly.
524 Backward links reset for non-owned hits in AliDevice destructor.
525 06-jul-2004 NvE AliCalorimeter hit I/O only via the linear array to decrease filesize on disk
526 and improve I/O speed.
527 Internal temp. arrays used for hit sorting in AliDevice and AliEvent and array
528 pointers returned instead of the arrays themselves. This will provide more
529 flexibility in usage.
530 Sorting and clustering procedures in AliCalorimeter modified to use TObjArray pointers
531 to enable direct use of the AliDevice linear sorting facility.
532 Default for AliDevice changed such that now all registered hits are by default owned
533 by the AliDevice object.
534 06-oct-2004 NvE Full support for data access via slotname specification introduced in AliAttrib and AliSignal.
535 07-oct-2004 NvE Docs of AliAttrib and AliSignal updated for new data access via slotname specification.
536 12-oct-2004 NvE Display facility introduced in AliDevice and device backward linking updated for
537 new "owning device" in AliSignal.
538 13-oct-2004 NvE Hit investigation facilities extended in AliDevice and AliEvent.
539 15-oct-2004 NvE Optimisation of MC parameters for nucleus-nucleus and astrophysics processes introduced
540 in AliCollider. Also facilities added to provide full user control.
541 26-nov-2004 NvE Printout of UniqueID added in AliSignal::Data() and AliEvent::ShowDevices() in view of
542 addressing specific signals or devices during data analysis.
543 Memberfunction GetIdHit introduced in AliDevice and AliEvent and AliJet::GetIdTrack
545 Memberfunction GetIdDevice introduced in AliEvent.
546 27-nov-2004 NvE Protection for j<1 introduced in AliSignal::SetWaveform().
547 The waveforms in AliSignal have now become completely decoupled from signal slots,
548 so support for setting waveforms by specifying a slotname has been removed.
549 Printout info in AliSignal::Data() and AliSignal::List() improved and memberfunctions
550 ListWaveform() and GetWaveformIndex() introduced in AliSignal.
551 28-nov-2004 NvE User definable status word introduced in AliDevice to allow indication of different
552 versions of readout electronics etc...
553 29-nov-2004 NvE Additional sub-directories (e.g. wa98) introduced which contain Ralice implementations
554 to serve data analysis efforts for various experiments.
555 01-dec-2004 NvE Install scripts like e.g. "gcclib" renamed to "gcclib.sh" etc... in /scripts.
556 The old scripts (i.e. without the .sh extension) will be deleted in due time.
557 12-jan-2005 NvE Bug fix in AliAttrib::GetSlotIndex() by exiting as soon as matching name is found.
558 20-jan-2005 NvE Modification in AliSignal::GetNwaveforms() to return last index instead of array
559 size to take into account the fact that a TObjArray always gets a default size
560 of 16 when reading data from a file.
561 Also the standard ROOT file libNew.lib is now automatically renamed to libNew.lix
562 in the Ralice windows installation script mklibs.bat to prevent linking with
563 this libNew.lib which is inconsistent with the binary ROOT executable release.
564 09-feb-2005 NvE New class AliTimestamp introduced to support timestamp information for
565 astrophysical research (i.e. Julian dates etc...) without the restrictions
567 10-feb-2005 NvE AliEvent modified such that it is derived from AliTimestamp.
568 This will allow events to be synchronised with astrophysical phenomena without
569 the restrictions imposed by TTimeStamp.
570 All existing user functions have been kept to provide full backward compatibility
571 in usage. However, a side effect of the new structure is that when reading data files
572 containing the old event structures, the original date/time stamp information is lost and
573 replaced by the date/time at the moment of reading the data.
574 This implies that to restore the original event date/time, the data files have to
575 be re-created. This I/O backward incompatibility could not be avoided in the
576 effort of eliminating the TTimeStamp restrictions.
577 04-mar-2005 NvE Installation scripts named amdgcclib.sh introduced in all /scripts directories to enable
578 shared library creation on AMD 64 (Athlon and Opteron) machines.
579 31-mar-2005 NvE AliObjMatrix derived from TNamed instead of from TObject to allow specification of
580 a name and title for this class.
581 13-apr-2005 NvE New memberfunctions SetFitDetails and GetFitDetails introduced in AliTrack
582 to enable a versatile facility to store details of various fit procedures
583 for a certain track. This new facility is based on the original idea of Adam Bouchta.
584 Destructor of AliSignal modified to remove the corresponding AliSignal instance
585 first from all related tracks before deleting the link matrix area.
586 14-apr-2005 NvE Functionality of ShowDevices extended in AliEvent. Also memberfunction HeaderData() modified
587 to prevent long output lists when many devices (and/or tracks) are present.
588 New memberfunction ShowTracks introduced in AliJet and memberfunction Data() updated.
589 18-apr-2005 NvE New memberfunction GetTracks introduced in AliJet to provide various track selections.
590 19-apr-2005 NvE Memberfunctions GetNtracks and GetTracks of AliJet extended in functionality.
591 20-apr-2005 NvE Id of owning device added to the output of AliSignal::Data().
592 10-may-2005 NvE Support for timestamps introduced in AliTrack and AliPosition.
593 Memberfunction GetX introduced in Ali3Vector for easy component access.
594 Picosecond support and calculation of time difference introduced in AliTimestamp
595 to enable investigation of both very short (i.e. time of flight analysis in
596 particle physics experiments) and very long (i.e. astrophysical phenomena)
598 17-may-2005 NvE Functionality of AliTimestamp extended w.r.t. treatment of time intervals and
599 accuracy bug fixed in the calculation of time difference.
600 19-may-2005 NvE AliTimestamp* pointer arguments supported in AliTimestamp::GetDifference for convenience
601 when investigating e.g. TOF or trigger times for tracks and/or hits in analysing
603 Also GetMJD() invoked in GetDifference to ensure to always have updated Julian parameters.
604 22-may-2005 NvE Class AliMath extended to provide full distribution functions of several standard
605 distributions (e.g. Binomial, Poisson, Gauss) and key statistics (e.g. Chi-squared,
606 Student's T, F-test) in view of analysis using Bayesian logic.
607 The various distributions are provided as TF1 objects.
608 In addition, functions to provide the P-values of the various key statistics are also
609 introduced to allow a classical frequentist analysis as well.
610 25-may-2005 NvE Declaration of unused variable pi removed in AliMath::StudentDist and explicit double
611 specification of integer first argument to pow() in AliMath::FratioPvalue in order
612 to prevent messages from the gcc compiler (thanks Dipo, Philippe and Peter).
613 02-jun-2005 NvE Bug fix in copy ctor of AliPosition and beginpoint etc... setting of AliTrack.
614 In AliTrack all points are now set after first deleting the existing AliPositionObj
615 object instead of using the Ali3Vector::Load() memberfunction.
616 The bug arose because of the extension of AliPosition with the possibility to
617 store an AliTimestamp. This made AliPosition differ from Ali3Vector w.r.t. datamembers.
618 Also "cout << endl;" introduced after the Pylist() call in AliCollider in order to
619 separate the Pythia event listing from subsequent output due to the mis-interpretation
620 of Fortran carriage-control characters on some systems.
621 17-jun-2005 NvE New class AliJob introduced to provide a flexible (physics) analysis environment.
622 Bug (forgotten ps transfer in AliTimestamp::SetTJD) fixed (thanks Federico Carminati).
623 22-jun-2005 NvE Specific job folder recursively removed from the generic AliJob folder environment
624 in the AliJob destructor before actually deleting the specific job folder itself.
625 Also main object pointer updated in case of a match with removal of object(s) from
626 the specific job environment.
627 23-jun-2005 NvE Creation of specific job folder made optionally in AliJob.
628 24-jun-2005 NvE Selection/overruling of specific job folder creation introduced in AliJob::ExecuteJob
629 and the AliJob (derived) instance explicitly removed from the ListOfTasks to prevent
630 ROOT crashing when closing after execution.
631 02-aug-2005 NvE Support for explicit (de)calibration functions introduced in AliAttrib.
632 03-aug-2005 NvE AliSignal::GetSignal has been extended to support various (de)calibration facilities.
633 Printout is now also provided in AliSignal::List when only calibration data exist
634 for AliDevice (or derived) objects.
635 05-aug-2005 NvE Typos fixed in AliAttrib::GetCalFunction and AliAttrib::GetDecalFunction which
636 erroneously always returned a null pointer.
637 10-aug-2005 NvE AliSignal::GetSignal extended with mode=8 to support dead flag of parent device
638 in conjunction with the dead flag of the signal itself.
639 07-oct-2005 NvE Support for the extended AliSignal::GetSignal (de)calibration facilities
640 introduced in memberfunctions SortHits, GetExtremes, Displayhits and SortDevices
641 of classes AliDevice and AliEvent.
642 Note : For DisplayHits this new signal correction mode replaces the marker style
643 specification parameter.
644 Also new memberfunction GetDevices introduced in AliEvent.
645 11-oct-2005 NvE SetMJD invoked at the end of AliTimestamp::Add instead of just updating the
646 various datamembers. In this way the TTimeStamp parameters are brought in sync
647 with the (modified) AliTimestamp values.
648 20-oct-2005 NvE Directory /macros introduced and ROOT macro makedocs.cc added in /macros
649 to provide a generic method to auto-create the html class documentation
650 on all supported platforms.
651 For further details see /macros/makedocs.cc.
652 24-oct-2005 NvE Protection introduced in AliJet::AddTrack to prevent multiple storage of
653 the same track in case no private copy of the track is made.
654 Memberfunction GetOpeningAngle introduced in Ali3Vector and Ali4Vector.
655 25-oct-2005 NvE Support introduced for user selectable angular units (rad or deg) in Ali3Vector,
656 Ali4Vector and all derived classes.
657 27-oct-2005 NvE Memberfunction GetX to access individual vector components also introduced
659 Also memberfunction SortJets introduced in AliVertex.
660 Misleading comment modified in AliDevice.cxx.
661 29-oct-2005 NvE Forgotten angular unit setting fixed w.r.t. begin point etc... in AliTrack::ListAll
662 ad begin point etc... info also added in AliTrack::List.
663 Memberfunction SortTracks introduced in AliJet and comment corrected in AliVertex.h.
664 07-nov-2005 NvE Macro makedocs.cc in directory /macros modified (i.e. ";" changed by ":") to make
665 it generic so that it works correctly on all platforms (thanks Axel Naumann).
666 08-nov-2005 NvE Sorting memberfunctions in AliDevice, AliVertex and AliJet optimised to save
667 CPU time. In case two values are identical no swap is performed.
668 Basically the test "val1 < val2" was replaced by "val1 <= val2".
669 09-nov-2005 NvE DisplayHits memberfunctions in AliDevice updated to fully support all
670 (de)calibration modes of GetSignal for displaying (and skipping dead) hits.
671 14-nov-2005 NvE Hit access by name introduced in AliDevice.
672 15-nov-2005 NvE Support for opening angle calculation between a 3-vector and the 3-vector part
673 of a 4-vector introduced in Ali4Vector.
674 16-nov-2005 NvE Support for a reference point introduced in AliJet.
675 06-dec-2005 NvE Memberfunction GetDistance() introduced in AliTrack to determine the
676 distance between a track and a certain position.
677 12-dec-2005 NvE Track selection by name introduced in AliJet.
678 23-feb-2006 NvE Support for automatic subtask(s) execution introduced in AliJob::ExecuteJob().
679 28-feb-2006 NvE Memberfunction ProcessObject() introduced in AliJob for convenience.
680 14-mar-2006 NvE RemoveTracks() facilities introduced in AliJet.
681 17-mar-2006 NvE Support for marker of track starting point introduced in AliHelix.
682 This allows observation of moving direction in event displays.
683 Also support for ignoring track endpoints introduced in AliHelix to
684 allow correct display for very long tracks together with observed hits.
685 18-mar-2006 NvE Support for display of selected track array introduced in AliHelix.
686 Also copy ctor of AliHelix made complete for new datamembers.
687 22-mar-2006 NvE Line attribute selections for displays extended in AliHelix.
688 20-apr-2006 NvE Several small modifications to prevent gcc warnings.
689 10-may-2006 NvE Distance determination between tracks and/or jets introduced in
691 Also compiler warnings activated for overloaded virtuals in installation
692 script for AMD Athlon in the /scripts sub-directory.
693 22-jun-2006 NvE Linear track storage facility introduced in AliSignal to enable
694 a lightweight signal <-> track backward linking facility instead of
695 the elaborate signal slot related links.
696 Also the functionality of AliTrack::AddSignal extended with specific modes.
697 Double_t replaced by Double32_t in Ali3Vector.h, Ali4Vector.h and AliBoost.h
698 and fDresult suppressed for I/O streaming. This will reduce the produced
700 21-jul-2006 NvE AliSample extended for computation of median.
701 12-sep-2006 NvE Memberfunctions GetNslots and AddNamedSlot introduced and various
702 modifications made in AliAttrib and AliSignal to overcome a ROOT
703 feature which always sets the size of TArray objects to a default
704 of 16 when reading these objects back from a file.
705 The modified AliAttrib and AliSignal don't rely on a GetSize()
706 anymore, but determine the number of stored values from the
707 actual array contents.
708 19-sep-2006 NvE Accuracy problem solved in Ali3Vector::GetOpeningAngle.
709 20-sep-2006 NvE AliSample::GetMedian corrected for empty or single value arrays.
710 25-sep-2006 NvE AliSample extended with memberfunction GetSpread() and also
711 support for providing minimum and maximum values introduced.
712 12-oct-2006 NvE New memberfunction GetNsignals introduced in AliJet and jet
713 ordering w.r.t. number of signals added in AliVertex.
714 19-oct-2006 NvE AliJet::GetNsignals modified to prevent double counting of
715 multiple occurrences of the same signal.
716 24-oct-2006 NvE AliJet and AliVertex extended with ordering w.r.t. charge.
717 26-oct-2006 NvE Energy/Momentum scale indicator introduced in AliTrack and AliJet
718 and support for chi2 and ndf datamembers removed from AliTrack.
719 The latter can be achieved in a more flexible way via the fit
720 details facility of AliTrack.
721 07-nov-2006 NvE Default unit scale changed from cm to meter in AliPosition
722 and support introduced for user selectable unit scale
723 in retrieval of position coordinates, errors and distances.
724 08-nov-2006 NvE User selectable unit scale introduced for retrieval of
725 physics parameters and distances in AliTrack and AliJet.
726 Also the track and jet sorting memberfunctions of AliJet
727 and AliVertex have been updated to use this new feature.
728 Also AliHelix has been updated to use this new feature and the
729 default meter metric scale.
730 09-nov-2006 NvE AliCollider updated to use new standard 1 meter metric units
731 and generator parameters stored in a device named "AliCollider".
732 Also beam/target datamembers removed from AliEvent and storage
733 of these beam/target parameters performed via a device named "Beam".
734 10-nov-2006 NvE Bug fixed in AliHelix.cxx such that the original reference point
735 of the track itself is not modified when the user had specified
736 a different scale. Also GetLastPoint() used in AliHelix to obtain
737 the index of the last point instead of relying on the dimension
738 of the points array as obtained with GetN(). This increases the
739 accuracy of extrapolation (and drawing) resuls since no undefined
740 points are now used anymore.
741 01-dec-2006 NvE AliTimestamp::Add() updated to allow specification of large time differences
742 also by giving e.g. only a certain number of seconds instead of explicitly
743 giving the time difference in elapsed days, remaining elapsed seconds etc...
744 This is very convenient by time manipulations based on GPS data.
745 The extension has been realised by just replacing the relevant if()
746 statements by while() loops in determining the remaining fractional counts.
747 Furthermore, some modulo operations have been introduced to prevent
749 08-dec-2006 NvE Memberfunctions SetUT introduced in AliTimestamp to provide convenient
750 ways to set a specific UT date/time.
