19Avoid overlap of slat volumes.
20
2c799aa2 21Revision 1.13 2000/10/26 07:33:44 morsch
22Correct x-position of slats in station 5.
23
8013c580 24Revision 1.12 2000/10/25 19:55:35 morsch
25Switches for each station individually for debug and lego.
26
b17c0c87 27Revision 1.11 2000/10/22 16:44:01 morsch
28Update of slat geometry for stations 3,4,5 (A. deFalco)
29
f9f7c205 30Revision 1.10 2000/10/12 16:07:04 gosset
31StepManager:
32* SigGenCond only called for tracking chambers,
33 hence no more division by 0,
34 and may use last ALIROOT/dummies.C with exception handling;
35* "10" replaced by "AliMUONConstants::NTrackingCh()".
36
a75f073c 37Revision 1.9 2000/10/06 15:37:22 morsch
38Problems with variable redefinition in for-loop solved.
39Variable names starting with u-case letters changed to l-case.
40
6c5ddcfa 41Revision 1.8 2000/10/06 09:06:31 morsch
42Include Slat chambers (stations 3-5) into geometry (A. de Falco)
43
1e8fff9c 44Revision 1.7 2000/10/02 21:28:09 fca
45Removal of useless dependecies via forward declarations
46
94de3818 47Revision 1.6 2000/10/02 17:20:45 egangler
48Cleaning of the code (continued ) :
49-> coding conventions
50-> void Streamers
51-> some useless includes removed or replaced by "class" statement
52
8c449e83 53Revision 1.5 2000/06/28 15:16:35 morsch
54(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
55to allow development of slat-muon chamber simulation and reconstruction code in the MUON
56framework. The changes should have no side effects (mostly dummy arguments).
57(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
58of chambers with overlapping modules (MakePadHits, Disintegration).
59
802a864d 60Revision 1.4 2000/06/26 14:02:38 morsch
61Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
