8c449e83 | 59 | Revision 1.5 2000/06/28 15:16:35 morsch |
60 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
61 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
62 | framework. The changes should have no side effects (mostly dummy arguments). | |
63 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
64 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
65 | ||
