8c449e83 18Revision 1.5 2000/06/28 15:16:35 morsch
19(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
20to allow development of slat-muon chamber simulation and reconstruction code in the MUON
21framework. The changes should have no side effects (mostly dummy arguments).
22(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
23of chambers with overlapping modules (MakePadHits, Disintegration).
24
