19Update of slat geometry for stations 3,4,5 (A. deFalco)
20
f9f7c205 21Revision 1.10 2000/10/12 16:07:04 gosset
22StepManager:
23* SigGenCond only called for tracking chambers,
24 hence no more division by 0,
25 and may use last ALIROOT/dummies.C with exception handling;
26* "10" replaced by "AliMUONConstants::NTrackingCh()".
27
a75f073c 28Revision 1.9 2000/10/06 15:37:22 morsch
29Problems with variable redefinition in for-loop solved.
30Variable names starting with u-case letters changed to l-case.
31
6c5ddcfa 32Revision 1.8 2000/10/06 09:06:31 morsch
33Include Slat chambers (stations 3-5) into geometry (A. de Falco)
34
1e8fff9c 35Revision 1.7 2000/10/02 21:28:09 fca
36Removal of useless dependecies via forward declarations
37
94de3818 38Revision 1.6 2000/10/02 17:20:45 egangler
39Cleaning of the code (continued ) :
40-> coding conventions
41-> void Streamers
42-> some useless includes removed or replaced by "class" statement
43
8c449e83 44Revision 1.5 2000/06/28 15:16:35 morsch
45(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
46to allow development of slat-muon chamber simulation and reconstruction code in the MUON
47framework. The changes should have no side effects (mostly dummy arguments).
48(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
49of chambers with overlapping modules (MakePadHits, Disintegration).
50
802a864d 51Revision 1.4 2000/06/26 14:02:38 morsch
52Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
