-Major upgrade of AliRoot code
-Revision 1.20 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
