23BuildGeometry of AliMUON for trigger chambers delegated to AliMUONSegmentationTriggerX (same strategy as for tracking chambers)
24
5fd73042 25Revision 1.38 2000/11/06 09:20:43 morsch
26AliMUON delegates part of BuildGeometry() to AliMUONSegmentation using the
27Draw() method. This avoids code and parameter replication.
28
aaf4addd 29Revision 1.37 2000/10/26 09:53:37 pcrochet

52Cleaning of the code :
53-> coding conventions
54-> void Streamers
55-> some useless includes removed or replaced by "class" statement
56

58SetAcceptance defines inner and outer chamber radii according to angular acceptance.
59Can be used for simple acceptance studies.

63
45085cb9 64Revision 1.27 2000/07/22 16:36:50 morsch
65Change order of indices in creation (new) of xhit and yhit
66
6b18d06a 67Revision 1.26 2000/07/03 11:54:57 morsch
68AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER
69The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC.
70
a30a000f 71Revision 1.25 2000/06/29 12:34:09 morsch
72AliMUONSegmentation class has been made independent of AliMUONChamber. This makes
73it usable with any other geometry class. The link to the object to which it belongs is
74established via an index. This assumes that there exists a global geometry manager
75from which the pointer to the parent object can be obtained (in our case gAlice).
76
d81db581 77Revision 1.24 2000/06/28 15:16:35 morsch
78(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
79to allow development of slat-muon chamber simulation and reconstruction code in the MUON
80framework. The changes should have no side effects (mostly dummy arguments).
81(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
82of chambers with overlapping modules (MakePadHits, Disintegration).
83
802a864d 84Revision 1.23 2000/06/28 12:19:17 morsch
85More consequent seperation of global input data services (AliMUONClusterInput singleton) and the
86cluster and hit reconstruction algorithms in AliMUONClusterFinderVS.
87AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction.
88It requires two cathode planes. Small modifications in the code will make it usable for
89one cathode plane and, hence, more general (for test beam data).
90AliMUONClusterFinder is now obsolete.
91
30aaba74 92Revision 1.22 2000/06/28 08:06:10 morsch
93Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the
94algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton.
95It also naturally takes care of the TMinuit instance.
96
9825400f 97Revision 1.21 2000/06/27 08:54:41 morsch
98Problems with on constant array sizes (in hitMap, nmuon, xhit, yhit) corrected.
