25Cleaning of the code (continued ) :
26-> coding conventions
27-> void Streamers
28-> some useless includes removed or replaced by "class" statement
29
8c449e83 30Revision 1.5 2000/06/28 15:16:35 morsch
31(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
32to allow development of slat-muon chamber simulation and reconstruction code in the MUON
33framework. The changes should have no side effects (mostly dummy arguments).
34(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
35of chambers with overlapping modules (MakePadHits, Disintegration).
36
802a864d 37Revision 1.4 2000/06/26 14:02:38 morsch
38Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
