a75f073c 18Revision 1.9 2000/10/06 15:37:22 morsch
19Problems with variable redefinition in for-loop solved.
20Variable names starting with u-case letters changed to l-case.

6c5ddcfa 22Revision 1.8 2000/10/06 09:06:31 morsch
23Include Slat chambers (stations 3-5) into geometry (A. de Falco)
24
1e8fff9c 25Revision 1.7 2000/10/02 21:28:09 fca
26Removal of useless dependecies via forward declarations
27
94de3818 28Revision 1.6 2000/10/02 17:20:45 egangler
29Cleaning of the code (continued ) :
30-> coding conventions
31-> void Streamers
32-> some useless includes removed or replaced by "class" statement
33
8c449e83 34Revision 1.5 2000/06/28 15:16:35 morsch
35(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
36to allow development of slat-muon chamber simulation and reconstruction code in the MUON
37framework. The changes should have no side effects (mostly dummy arguments).
38(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
39of chambers with overlapping modules (MakePadHits, Disintegration).
40
802a864d 41Revision 1.4 2000/06/26 14:02:38 morsch
42Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
