18 Revision 1.15 2000/11/06 11:39:02 morsch
19 Bug in StepManager() corrected.
21 Revision 1.14 2000/11/06 09:16:50 morsch
22 Avoid overlap of slat volumes.
24 Revision 1.13 2000/10/26 07:33:44 morsch
25 Correct x-position of slats in station 5.
27 Revision 1.12 2000/10/25 19:55:35 morsch
28 Switches for each station individually for debug and lego.
30 Revision 1.11 2000/10/22 16:44:01 morsch
31 Update of slat geometry for stations 3,4,5 (A. deFalco)
33 Revision 1.10 2000/10/12 16:07:04 gosset
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()".
40 Revision 1.9 2000/10/06 15:37:22 morsch
41 Problems with variable redefinition in for-loop solved.
42 Variable names starting with u-case letters changed to l-case.
44 Revision 1.8 2000/10/06 09:06:31 morsch
45 Include Slat chambers (stations 3-5) into geometry (A. de Falco)
47 Revision 1.7 2000/10/02 21:28:09 fca
48 Removal of useless dependecies via forward declarations
50 Revision 1.6 2000/10/02 17:20:45 egangler
51 Cleaning of the code (continued ) :
54 -> some useless includes removed or replaced by "class" statement
56 Revision 1.5 2000/06/28 15:16:35 morsch
57 (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
58 to allow development of slat-muon chamber simulation and reconstruction code in the MUON
59 framework. The changes should have no side effects (mostly dummy arguments).
60 (2) Hit disintegration uses 3-dim hit coordinates to allow simulation
61 of chambers with overlapping modules (MakePadHits, Disintegration).
63 Revision 1.4 2000/06/26 14:02:38 morsch
64 Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
66 Revision 1.3 2000/06/22 14:10:05 morsch
67 HP scope problems corrected (PH)
69 Revision 1.2 2000/06/15 07:58:49 morsch
70 Code from MUON-dev joined
72 Revision 1.1.2.14 2000/06/14 14:37:25 morsch
73 Initialization of TriggerCircuit added (PC)
75 Revision 1.1.2.13 2000/06/09 21:55:47 morsch
76 Most coding rule violations corrected.
78 Revision 1.1.2.12 2000/05/05 11:34:29 morsch
81 Revision 1.1.2.11 2000/05/05 10:06:48 morsch
82 Coding Rule violations regarding trigger section corrected (CP)
83 Log messages included.
