d81db581 18Revision 1.4 2000/06/29 06:52:02 pcrochet
19pow changed to TMath::Power

39f5a0e6 21Revision 1.3 2000/06/28 15:16:35 morsch
22(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
23to allow development of slat-muon chamber simulation and reconstruction code in the MUON
24framework. The changes should have no side effects (mostly dummy arguments).
25(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
26of chambers with overlapping modules (MakePadHits, Disintegration).

34Revision 1.1.2.2 2000/04/26 12:28:25 morsch
35- flag pad hits with condition on ToF (CP)
36- Tof included in the method DisIntegration (CP)
