-Revision 1.6 2001/02/05 14:49:29 hristov
-Compare() declared const (R.Brun)
-
-Revision 1.5 2000/07/20 12:45:27 gosset
-New "EventReconstructor..." structure,
- hopefully more adapted to tree/streamer.
-"AliMUONEventReconstructor::RemoveDoubleTracks"
- to keep only one track among similar ones.
-
-Revision 1.4 2000/07/18 16:04:06 gosset
-AliMUONEventReconstructor package:
-* a few minor modifications and more comments
-* a few corrections
- * right sign for Z of raw clusters
- * right loop over chambers inside station
- * symmetrized covariance matrix for measurements (TrackChi2MCS)
- * right sign of charge in extrapolation (ExtrapToZ)
- * right zEndAbsorber for Branson correction below 3 degrees
-* use of TVirtualFitter instead of TMinuit for AliMUONTrack::Fit
-* no parameter for AliMUONTrack::Fit() but more fit parameters in Track object
-
-Revision 1.3 2000/06/25 13:06:39 hristov
-Inline functions moved from *.cxx to *.h files instead of forward declarations
-
-Revision 1.2 2000/06/15 07:58:49 morsch
-Code from MUON-dev joined
-
-Revision 1.1.2.3 2000/06/12 10:11:45 morsch
-Dummy copy constructor and assignment operator added
-
-Revision 1.1.2.2 2000/06/09 12:58:05 gosset
-Removed comment beginnings in Log sections of .cxx files
-Suppressed most violations of coding rules
-
-Revision 1.1.2.1 2000/06/07 14:44:53 gosset
-Addition of files for track reconstruction in C++
