+07-oct-2004 NvE Docs of AliAttrib and AliSignal updated for new data access via slotname specification.
+12-oct-2004 NvE Display facility introduced in AliDevice and device backward linking updated for
+ new "owning device" in AliSignal.
+13-oct-2004 NvE Hit investigation facilities extended in AliDevice and AliEvent.
+15-oct-2004 NvE Optimisation of MC parameters for nucleus-nucleus and astrophysics processes introduced
+ in AliCollider. Also facilities added to provide full user control.
+26-nov-2004 NvE Printout of UniqueID added in AliSignal::Data() and AliEvent::ShowDevices() in view of
+ addressing specific signals or devices during data analysis.
+ Memberfunction GetIdHit introduced in AliDevice and AliEvent and AliJet::GetIdTrack
+ optimised for speed.
+ Memberfunction GetIdDevice introduced in AliEvent.
+27-nov-2004 NvE Protection for j<1 introduced in AliSignal::SetWaveform().
+ The waveforms in AliSignal have now become completely decoupled from signal slots,
+ so support for setting waveforms by specifying a slotname has been removed.
+ Printout info in AliSignal::Data() and AliSignal::List() improved and memberfunctions
+ ListWaveform() and GetWaveformIndex() introduced in AliSignal.
+28-nov-2004 NvE User definable status word introduced in AliDevice to allow indication of different
+ versions of readout electronics etc...
+29-nov-2004 NvE Additional sub-directories (e.g. wa98) introduced which contain Ralice implementations
+ to serve data analysis efforts for various experiments.
+01-dec-2004 NvE Install scripts like e.g. "gcclib" renamed to "gcclib.sh" etc... in /scripts.
+ The old scripts (i.e. without the .sh extension) will be deleted in due time.
+12-jan-2005 NvE Bug fix in AliAttrib::GetSlotIndex() by exiting as soon as matching name is found.
+20-jan-2005 NvE Modification in AliSignal::GetNwaveforms() to return last index instead of array
+ size to take into account the fact that a TObjArray always gets a default size
+ of 16 when reading data from a file.
+ Also the standard ROOT file libNew.lib is now automatically renamed to libNew.lix
+ in the Ralice windows installation script mklibs.bat to prevent linking with
+ this libNew.lib which is inconsistent with the binary ROOT executable release.
+09-feb-2005 NvE New class AliTimestamp introduced to support timestamp information for
+ astrophysical research (i.e. Julian dates etc...) without the restrictions
+ of class TTimeStamp.
+10-feb-2005 NvE AliEvent modified such that it is derived from AliTimestamp.
+ This will allow events to be synchronised with astrophysical phenomena without
+ the restrictions imposed by TTimeStamp.
+ All existing user functions have been kept to provide full backward compatibility
+ in usage. However, a side effect of the new structure is that when reading data files
+ containing the old event structures, the original date/time stamp information is lost and
+ replaced by the date/time at the moment of reading the data.
+ This implies that to restore the original event date/time, the data files have to
+ be re-created. This I/O backward incompatibility could not be avoided in the
+ effort of eliminating the TTimeStamp restrictions.
+04-mar-2005 NvE Installation scripts named amdgcclib.sh introduced in all /scripts directories to enable
+ shared library creation on AMD 64 (Athlon and Opteron) machines.
+31-mar-2005 NvE AliObjMatrix derived from TNamed instead of from TObject to allow specification of
+ a name and title for this class.
+13-apr-2005 NvE New memberfunctions SetFitDetails and GetFitDetails introduced in AliTrack
+ to enable a versatile facility to store details of various fit procedures
+ for a certain track. This new facility is based on the original idea of Adam Bouchta.
+ Destructor of AliSignal modified to remove the corresponding AliSignal instance
+ first from all related tracks before deleting the link matrix area.
+14-apr-2005 NvE Functionality of ShowDevices extended in AliEvent. Also memberfunction HeaderData() modified
+ to prevent long output lists when many devices (and/or tracks) are present.
+ New memberfunction ShowTracks introduced in AliJet and memberfunction Data() updated.
+18-apr-2005 NvE New memberfunction GetTracks introduced in AliJet to provide various track selections.
+19-apr-2005 NvE Memberfunctions GetNtracks and GetTracks of AliJet extended in functionality.
+20-apr-2005 NvE Id of owning device added to the output of AliSignal::Data().
+10-may-2005 NvE Support for timestamps introduced in AliTrack and AliPosition.
+ Memberfunction GetX introduced in Ali3Vector for easy component access.
+ Picosecond support and calculation of time difference introduced in AliTimestamp
+ to enable investigation of both very short (i.e. time of flight analysis in
+ particle physics experiments) and very long (i.e. astrophysical phenomena)
+ time intervals.
+17-may-2005 NvE Functionality of AliTimestamp extended w.r.t. treatment of time intervals and
+ accuracy bug fixed in the calculation of time difference.
+19-may-2005 NvE AliTimestamp* pointer arguments supported in AliTimestamp::GetDifference for convenience
+ when investigating e.g. TOF or trigger times for tracks and/or hits in analysing
+ AliEvent structures.
+ Also GetMJD() invoked in GetDifference to ensure to always have updated Julian parameters.
+22-may-2005 NvE Class AliMath extended to provide full distribution functions of several standard
+ distributions (e.g. Binomial, Poisson, Gauss) and key statistics (e.g. Chi-squared,
+ Student's T, F-test) in view of analysis using Bayesian logic.
+ The various distributions are provided as TF1 objects.
+ In addition, functions to provide the P-values of the various key statistics are also
+ introduced to allow a classical frequentist analysis as well.
+25-may-2005 NvE Declaration of unused variable pi removed in AliMath::StudentDist and explicit double
+ specification of integer first argument to pow() in AliMath::FratioPvalue in order
+ to prevent messages from the gcc compiler (thanks Dipo, Philippe and Peter).
+02-jun-2005 NvE Bug fix in copy ctor of AliPosition and beginpoint etc... setting of AliTrack.
+ In AliTrack all points are now set after first deleting the existing AliPositionObj
+ object instead of using the Ali3Vector::Load() memberfunction.
+ The bug arose because of the extension of AliPosition with the possibility to
+ store an AliTimestamp. This made AliPosition differ from Ali3Vector w.r.t. datamembers.
+ Also "cout << endl;" introduced after the Pylist() call in AliCollider in order to
+ separate the Pythia event listing from subsequent output due to the mis-interpretation
+ of Fortran carriage-control characters on some systems.
+17-jun-2005 NvE New class AliJob introduced to provide a flexible (physics) analysis environment.
+ Bug (forgotten ps transfer in AliTimestamp::SetTJD) fixed (thanks Federico Carminati).
+22-jun-2005 NvE Specific job folder recursively removed from the generic AliJob folder environment
+ in the AliJob destructor before actually deleting the specific job folder itself.
+ Also main object pointer updated in case of a match with removal of object(s) from
+ the specific job environment.
+23-jun-2005 NvE Creation of specific job folder made optionally in AliJob.
+24-jun-2005 NvE Selection/overruling of specific job folder creation introduced in AliJob::ExecuteJob
+ and the AliJob (derived) instance explicitly removed from the ListOfTasks to prevent
+ ROOT crashing when closing after execution.
+02-aug-2005 NvE Support for explicit (de)calibration functions introduced in AliAttrib.
+03-aug-2005 NvE AliSignal::GetSignal has been extended to support various (de)calibration facilities.
+ Printout is now also provided in AliSignal::List when only calibration data exist
+ for AliDevice (or derived) objects.
+05-aug-2005 NvE Typos fixed in AliAttrib::GetCalFunction and AliAttrib::GetDecalFunction which
+ erroneously always returned a null pointer.
+10-aug-2005 NvE AliSignal::GetSignal extended with mode=8 to support dead flag of parent device
+ in conjunction with the dead flag of the signal itself.
+07-oct-2005 NvE Support for the extended AliSignal::GetSignal (de)calibration facilities
+ introduced in memberfunctions SortHits, GetExtremes, Displayhits and SortDevices
+ of classes AliDevice and AliEvent.
+ Note : For DisplayHits this new signal correction mode replaces the marker style
+ specification parameter.
+ Also new memberfunction GetDevices introduced in AliEvent.
+11-oct-2005 NvE SetMJD invoked at the end of AliTimestamp::Add instead of just updating the
+ various datamembers. In this way the TTimeStamp parameters are brought in sync
+ with the (modified) AliTimestamp values.
+20-oct-2005 NvE Directory /macros introduced and ROOT macro makedocs.cc added in /macros
+ to provide a generic method to auto-create the html class documentation
+ on all supported platforms.

+ for Ali4Vector.
+ Also memberfunction SortJets introduced in AliVertex.
+ Misleading comment modified in AliDevice.cxx.
+29-oct-2005 NvE Forgotten angular unit setting fixed w.r.t. begin point etc... in AliTrack::ListAll
+ ad begin point etc... info also added in AliTrack::List.
+ Memberfunction SortTracks introduced in AliJet and comment corrected in AliVertex.h.
+07-nov-2005 NvE Macro makedocs.cc in directory /macros modified (i.e. ";" changed by ":") to make
+ it generic so that it works correctly on all platforms (thanks Axel Naumann).
+08-nov-2005 NvE Sorting memberfunctions in AliDevice, AliVertex and AliJet optimised to save
+ CPU time. In case two values are identical no swap is performed.
+ Basically the test "val1 < val2" was replaced by "val1 <= val2".
+09-nov-2005 NvE DisplayHits memberfunctions in AliDevice updated to fully support all
+ (de)calibration modes of GetSignal for displaying (and skipping dead) hits.
+14-nov-2005 NvE Hit access by name introduced in AliDevice.

+ Also support for ignoring track endpoints introduced in AliHelix to
+ allow correct display for very long tracks together with observed hits.
+18-mar-2006 NvE Support for display of selected track array introduced in AliHelix.
+ Also copy ctor of AliHelix made complete for new datamembers.
+22-mar-2006 NvE Line attribute selections for displays extended in AliHelix.
+20-apr-2006 NvE Several small modifications to prevent gcc warnings.
+10-may-2006 NvE Distance determination between tracks and/or jets introduced in
+ AliTrack and AliJet.
+ Also compiler warnings activated for overloaded virtuals in installation
+ script for AMD Athlon in the /scripts sub-directory.
+22-jun-2006 NvE Linear track storage facility introduced in AliSignal to enable
+ a lightweight signal <-> track backward linking facility instead of
+ the elaborate signal slot related links.
+ Also the functionality of AliTrack::AddSignal extended with specific modes.
+ Double_t replaced by Double32_t in Ali3Vector.h, Ali4Vector.h and AliBoost.h
+ and fDresult suppressed for I/O streaming. This will reduce the produced
+ output filesize.
+21-jul-2006 NvE AliSample extended for computation of median.
+12-sep-2006 NvE Memberfunctions GetNslots and AddNamedSlot introduced and various
+ modifications made in AliAttrib and AliSignal to overcome a ROOT
+ feature which always sets the size of TArray objects to a default
+ of 16 when reading these objects back from a file.
+ The modified AliAttrib and AliSignal don't rely on a GetSize()
+ anymore, but determine the number of stored values from the
+ actual array contents.
+19-sep-2006 NvE Accuracy problem solved in Ali3Vector::GetOpeningAngle.
+20-sep-2006 NvE AliSample::GetMedian corrected for empty or single value arrays.
+25-sep-2006 NvE AliSample extended with memberfunction GetSpread() and also
+ support for providing minimum and maximum values introduced.
+12-oct-2006 NvE New memberfunction GetNsignals introduced in AliJet and jet
+ ordering w.r.t. number of signals added in AliVertex.
+19-oct-2006 NvE AliJet::GetNsignals modified to prevent double counting of
+ multiple occurrences of the same signal.
+24-oct-2006 NvE AliJet and AliVertex extended with ordering w.r.t. charge.
+26-oct-2006 NvE Energy/Momentum scale indicator introduced in AliTrack and AliJet
+ and support for chi2 and ndf datamembers removed from AliTrack.
+ The latter can be achieved in a more flexible way via the fit
+ details facility of AliTrack.
+07-nov-2006 NvE Default unit scale changed from cm to meter in AliPosition
+ and support introduced for user selectable unit scale
+ in retrieval of position coordinates, errors and distances.
+08-nov-2006 NvE User selectable unit scale introduced for retrieval of
+ physics parameters and distances in AliTrack and AliJet.

+ and generator parameters stored in a device named "AliCollider".
+ Also beam/target datamembers removed from AliEvent and storage
+ of these beam/target parameters performed via a device named "Beam".
+10-nov-2006 NvE Bug fixed in AliHelix.cxx such that the original reference point
+ of the track itself is not modified when the user had specified
+ a different scale. Also GetLastPoint() used in AliHelix to obtain
+ the index of the last point instead of relying on the dimension
+ of the points array as obtained with GetN(). This increases the
+ accuracy of extrapolation (and drawing) resuls since no undefined
+ points are now used anymore.
+01-dec-2006 NvE AliTimestamp::Add() updated to allow specification of large time differences
+ also by giving e.g. only a certain number of seconds instead of explicitly
+ giving the time difference in elapsed days, remaining elapsed seconds etc...
+ This is very convenient by time manipulations based on GPS data.
+ The extension has been realised by just replacing the relevant if()
+ statements by while() loops in determining the remaining fractional counts.
+ Furthermore, some modulo operations have been introduced to prevent
+ integer overflows.
+08-dec-2006 NvE Memberfunctions SetUT introduced in AliTimestamp to provide convenient
+ ways to set a specific UT date/time.

+ accessible even for cases which fall outside the TTimeStamp range.
+ As such, the UT and GST info will always be provided via the Date()
+ memberfunction.
+16-mar-2007 NvE Uniform data format introduced for printout of AliTimestamp::Date().
+17-mar-2007 NvE AliTimestamp extended to allow local time printout for a specified offset
+ and addition of a time difference specified as (fractional) hours.
+ Also bug fixed in the fractional hour conversion facility.
+20-mar-2007 NvE Support for retrieval of Local Time (LT) and Local Sidereal Time (LST)
+ introduced in AliTimestamp.
+22-mar-2007 NvE Support introduced for setting of timestamp parameters based on Local Time (LT)
+ in AliTimestamp.
+25-mar-2007 NvE AliTimestamp extended with Apparent Sidereal Time.
+27-mar-2007 NvE Test on date/time validity corrected in AliTimestamp::SetMJD to prevent

+ ecliptic longitude due to nutation in AliTimestamp::GetGAST.
+28-mar-2007 NvE AliTimestamp::Date extended to provide apparent sidereal time via
+ specification of negative "mode" parameter.

+ Also AliJet extended with GetNtracks for a specified track name.
+27-sep-2007 NvE New memberfunction RemoveDevice() introduced in AliEvent.
+ AliAstrolab derived from TTask, to provide a base class for TTask
+ based processors.
+ New class AliEventSelector introduced.
+03-oct-2007 NvE Class AliMath extended with statistical analysis facilities
+ PsiValue and Chi2Value to investigate statistical significance
+ of observations in counting experiments.
+06-oct-2007 NvE Memberfunctions Chi2Value of class AliMath extended with ndf determination.
+09-oct-2007 NvE Memberfunctions ResetSignals and DeleteSignals of class AliSignal
+ extended with options to preserve the waveform histo contents.
+ These new options are now also used in the SetSignal and SetSignalError
+ memberfunctions of class AliSignal.
+15-oct-2007 NvE Typo corrected in docs of AliAstrolab.cxx and memberfunctions GetMedian
+ and GetSpread of AliSample.cxx extended for Y-values of histo data.

+ work by Garmt de Vries-Uiterweerd.
+09-nov-2007 GdV Automatic central meridian setting only activated when meridian
+ has a value smaller than -pi. This will allow also negative values
+ as user input.

+
+
