-Revision 1.10 2001/04/09 12:25:09 gosset
-Inversion of covariance matrices with local copy of TMinuit::mnvert,
-for symmetric positive definite matrices, instead of TMatrixD::Invert
-
-Revision 1.9 2001/01/17 20:59:24 hristov
-chPrev initialised
-
-Revision 1.8 2001/01/08 11:01:02 gosset
-Modifications used for addendum to Dimuon TDR (JP Cussonneau):
-*. MaxBendingMomentum to make both a segment and a track (default 500)
-*. MaxChi2 per degree of freedom to make a track (default 100)
-*. MinBendingMomentum used also to make a track
- and not only a segment (default 3)
-*. wider roads for track search in stations 1 to 3
-*. extrapolation to actual Z instead of Z(chamber) in FollowTracks
-*. in track fit:
- - limits on parameters X and Y (+/-500)
- - covariance matrices in double precision
- - normalization of covariance matrices before inversion
- - suppression of Minuit printouts
-*. correction against memory leak (delete extrapHit) in FollowTracks
-*. RMax to 10 degrees with Z(chamber) instead of fixed values;
- RMin and Rmax cuts suppressed in NewHitForRecFromGEANT,
- because useless with realistic geometry
-
-Revision 1.7 2000/09/19 15:50:46 gosset
-TrackChi2MCS function: covariance matrix better calculated,
-taking into account missing planes...
-
-Revision 1.6 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 1.5 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 1.4 2000/06/30 10:15:48 gosset
-Changes to EventReconstructor...:
-precision fit with multiple Coulomb scattering;
-extrapolation to vertex with Branson correction in absorber (JPC)
-
-Revision 1.3 2000/06/25 13:23:28 hristov
-stdlib.h needed for non-Linux compilation
-
-Revision 1.2 2000/06/15 07:58:48 morsch
-Code from MUON-dev joined
-
-Revision 1.1.2.3 2000/06/12 10:11:34 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++
