+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
+
