25 Revision 1.9 2000/10/06 15:37:22 morsch
26 Problems with variable redefinition in for-loop solved.
27 Variable names starting with u-case letters changed to l-case.
29 Revision 1.8 2000/10/06 09:06:31 morsch
30 Include Slat chambers (stations 3-5) into geometry (A. de Falco)
32 Revision 1.7 2000/10/02 21:28:09 fca
33 Removal of useless dependecies via forward declarations
35 Revision 1.6 2000/10/02 17:20:45 egangler
36 Cleaning of the code (continued ) :
39 -> some useless includes removed or replaced by "class" statement
41 Revision 1.5 2000/06/28 15:16:35 morsch
42 (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
43 to allow development of slat-muon chamber simulation and reconstruction code in the MUON
44 framework. The changes should have no side effects (mostly dummy arguments).
45 (2) Hit disintegration uses 3-dim hit coordinates to allow simulation
46 of chambers with overlapping modules (MakePadHits, Disintegration).
48 Revision 1.4 2000/06/26 14:02:38 morsch
49 Add class AliMUONConstants with MUON specific constants using static memeber data and access methods.
51 Revision 1.3 2000/06/22 14:10:05 morsch
52 HP scope problems corrected (PH)
54 Revision 1.2 2000/06/15 07:58:49 morsch
55 Code from MUON-dev joined
57 Revision 1.1.2.14 2000/06/14 14:37:25 morsch
58 Initialization of TriggerCircuit added (PC)
60 Revision 1.1.2.13 2000/06/09 21:55:47 morsch
61 Most coding rule violations corrected.
63 Revision 1.1.2.12 2000/05/05 11:34:29 morsch
66 Revision 1.1.2.11 2000/05/05 10:06:48 morsch
67 Coding Rule violations regarding trigger section corrected (CP)
68 Log messages included.
