34Update of slat geometry for stations 3,4,5 (A. deFalco)
35
f9f7c205 36Revision 1.10 2000/10/12 16:07:04 gosset
37StepManager:
38* SigGenCond only called for tracking chambers,
39 hence no more division by 0,
40 and may use last ALIROOT/dummies.C with exception handling;
41* "10" replaced by "AliMUONConstants::NTrackingCh()".
42
a75f073c 43Revision 1.9 2000/10/06 15:37:22 morsch
44Problems with variable redefinition in for-loop solved.
45Variable names starting with u-case letters changed to l-case.

51Removal of useless dependecies via forward declarations
52
94de3818 53Revision 1.6 2000/10/02 17:20:45 egangler
54Cleaning of the code (continued ) :
55-> coding conventions
56-> void Streamers
57-> some useless includes removed or replaced by "class" statement
58
8c449e83 59Revision 1.5 2000/06/28 15:16:35 morsch
60(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
61to allow development of slat-muon chamber simulation and reconstruction code in the MUON
62framework. The changes should have no side effects (mostly dummy arguments).
63(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
64of chambers with overlapping modules (MakePadHits, Disintegration).
65
802a864d 66Revision 1.4 2000/06/26 14:02:38 morsch
