e3cf5faa 21Revision 1.14 2000/11/06 09:16:50 morsch
22Avoid overlap of slat volumes.
23
2c799aa2 24Revision 1.13 2000/10/26 07:33:44 morsch
25Correct x-position of slats in station 5.
26
8013c580 27Revision 1.12 2000/10/25 19:55:35 morsch
28Switches for each station individually for debug and lego.

b17c0c87 30Revision 1.11 2000/10/22 16:44:01 morsch
31Update of slat geometry for stations 3,4,5 (A. deFalco)
32
f9f7c205 33Revision 1.10 2000/10/12 16:07:04 gosset
34StepManager:
35* SigGenCond only called for tracking chambers,
36 hence no more division by 0,
37 and may use last ALIROOT/dummies.C with exception handling;
38* "10" replaced by "AliMUONConstants::NTrackingCh()".
39
a75f073c 40Revision 1.9 2000/10/06 15:37:22 morsch
41Problems with variable redefinition in for-loop solved.
42Variable names starting with u-case letters changed to l-case.
43
6c5ddcfa 44Revision 1.8 2000/10/06 09:06:31 morsch
45Include Slat chambers (stations 3-5) into geometry (A. de Falco)
46

48Removal of useless dependecies via forward declarations
49
94de3818 50Revision 1.6 2000/10/02 17:20:45 egangler
51Cleaning of the code (continued ) :
52-> coding conventions
53-> void Streamers
54-> some useless includes removed or replaced by "class" statement
55
8c449e83 56Revision 1.5 2000/06/28 15:16:35 morsch
57(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
58to allow development of slat-muon chamber simulation and reconstruction code in the MUON
59framework. The changes should have no side effects (mostly dummy arguments).
60(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
61of chambers with overlapping modules (MakePadHits, Disintegration).
62
802a864d 63Revision 1.4 2000/06/26 14:02:38 morsch
