-Revision 1.21 2001/05/18 08:54:59 morsch
-Bug in decision on splitting corrected.
-
-Revision 1.20 2001/04/12 12:22:26 morsch
-- some numerical problems caused by pad staggering cured.
-- treatment of 1-2 and 2-1 ghosts
-- debuglevel > 1 prints introduced
-
-Revision 1.19 2001/03/20 13:32:10 egangler
-Code introduced to remove ghosts with the charge correlation between the 2
-cathods. A chi2 is performed for the 2 possibilities.
-If one gets good chi2 (with respect to the fGhostChi2Cut parameter) and the
-other wrong chi2, the ambiguity is solved
-If both gets good or both bad chi2, no choice is made
-By default the fGhostChi2Cut parameter is set to solve about 70% of ghost
-problems with about 2% errors, with the current version of the code.
-
-Implementation :
-fGhostChi2Cut is in AliMUONClusterFinderVS, with setters and getters.
-a fDebugLevel was also introduced to switch off some of the output.
-When an ambiguity is detected and not solved, the fGhost word in
-AliMUONRawCluster is set to 1 or 2, depending whether both charge chi2 are
-good or bad.
-a DumpIndex method was also added in AliMUONRawCluster to produce a printout
-of digit indexes.
-
-User incidences :
-By default, the code makes ghost check. If you want previous behaviour,
-put in MUONrawclusters the value of SetGhostChi2Cut to infinity (1e.6) is
-sufficient.
-
-Revision 1.18 2001/01/26 21:37:53 morsch
-Use access functions to AliMUONDigit member data.
-
-Revision 1.17 2001/01/23 18:58:19 hristov
-Initialisation of some pointers
-
-Revision 1.16 2000/12/21 23:27:30 morsch
-Error in argument list of AddRawCluster corrected.
-
-Revision 1.15 2000/12/21 22:14:38 morsch
-Clean-up of coding rule violations.
-
-Revision 1.14 2000/10/23 16:03:45 morsch
-Correct z-position of all clusters created "on the flight".
-
-Revision 1.13 2000/10/23 13:38:23 morsch
-Set correct z-coordinate when cluster is split.
-
-Revision 1.12 2000/10/18 11:42:06 morsch
-- AliMUONRawCluster contains z-position.
-- Some clean-up of useless print statements during initialisations.
-
-Revision 1.11 2000/10/06 09:04:05 morsch
-- Dummy z-arguments in GetPadI, SetHit, FirstPad replaced by real z-coordinate
- to make code work with slat chambers (AM)
-- Replace GetPadI calls with unchecked x,y coordinates by pad iterator calls wherever possible.
-
-Revision 1.10 2000/10/03 13:51:57 egangler
-Removal of useless dependencies via forward declarations
-
-Revision 1.9 2000/10/02 16:58:29 egangler
-Cleaning of the code :
--> coding conventions
--> void Streamers
--> some useless includes removed or replaced by "class" statement
-
-Revision 1.8 2000/07/03 11:54:57 morsch
-AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
-The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
-
-Revision 1.7 2000/06/28 15:16:35 morsch
-(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
-to allow development of slat-muon chamber simulation and reconstruction code in the MUON
-framework. The changes should have no side effects (mostly dummy arguments).
-(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
-of chambers with overlapping modules (MakePadHits, Disintegration).
-
-Revision 1.6 2000/06/28 12:19:18 morsch
-More consequent seperation of global input data services (AliMUONClusterInput singleton) and the
-cluster and hit reconstruction algorithms in AliMUONClusterFinderVS.
-AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction.
-It requires two cathode planes. Small modifications in the code will make it usable for
-one cathode plane and, hence, more general (for test beam data).
-AliMUONClusterFinder is now obsolete.
-
-Revision 1.5 2000/06/28 08:06:10 morsch
-Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the
-algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton.
-It also naturally takes care of the TMinuit instance.
-
-Revision 1.4 2000/06/27 16:18:47 gosset
-Finally correct implementation of xm, ym, ixm, iym sizes
-when at least three local maxima on cathode 1 or on cathode 2
-
-Revision 1.3 2000/06/22 14:02:45 morsch
-Parameterised size of xm[], ym[], ixm[], iym[] correctly implemented (PH)
-Some HP scope problems corrected (PH)
-
-Revision 1.2 2000/06/15 07:58:48 morsch
-Code from MUON-dev joined
-
-Revision 1.1.2.3 2000/06/09 21:58:33 morsch
-Most coding rule violations corrected.
-
-Revision 1.1.2.2 2000/02/15 08:33:52 morsch
-Error in calculation of contribution map for double clusters (Split method) corrected (A.M.)
-Error in determination of track list for double cluster (FillCluster method) corrected (A.M.)
-Revised and extended SplitByLocalMaxima method (Isabelle Chevrot):
- - For clusters with more than 2 maxima on one of the cathode planes all valid
- combinations of maxima on the two cathodes are preserved. The position of the maxima is
- taken as the hit position.
- - New FillCluster method with 2 arguments to find tracks associated to the clusters
- defined above added. (Method destinction by argument list not very elegant in this case,
- should be revides (A.M.)
- - Bug in if-statement to handle maximum 1 maximum per plane corrected
- - Two cluster per cathode but only 1 combination valid is handled.
- - More rigerous treatment of 1-2 and 2-1 combinations of maxima.
