b17c0c87 21Revision 1.11 2000/10/22 16:44:01 morsch
22Update of slat geometry for stations 3,4,5 (A. deFalco)
23
f9f7c205 24Revision 1.10 2000/10/12 16:07:04 gosset
25StepManager:
26* SigGenCond only called for tracking chambers,
27 hence no more division by 0,
28 and may use last ALIROOT/dummies.C with exception handling;
29* "10" replaced by "AliMUONConstants::NTrackingCh()".
30
a75f073c 31Revision 1.9 2000/10/06 15:37:22 morsch
32Problems with variable redefinition in for-loop solved.
33Variable names starting with u-case letters changed to l-case.
34
6c5ddcfa 35Revision 1.8 2000/10/06 09:06:31 morsch
36Include Slat chambers (stations 3-5) into geometry (A. de Falco)
37

39Removal of useless dependecies via forward declarations
40
94de3818 41Revision 1.6 2000/10/02 17:20:45 egangler
42Cleaning of the code (continued ) :
43-> coding conventions
44-> void Streamers
45-> some useless includes removed or replaced by "class" statement
46
8c449e83 47Revision 1.5 2000/06/28 15:16:35 morsch
48(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
49to allow development of slat-muon chamber simulation and reconstruction code in the MUON
50framework. The changes should have no side effects (mostly dummy arguments).
51(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
52of chambers with overlapping modules (MakePadHits, Disintegration).
53
802a864d 54Revision 1.4 2000/06/26 14:02:38 morsch
55Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
