d81db581 17Revision 1.24 2000/06/28 15:16:35 morsch
18(1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there)
19to allow development of slat-muon chamber simulation and reconstruction code in the MUON
20framework. The changes should have no side effects (mostly dummy arguments).
21(2) Hit disintegration uses 3-dim hit coordinates to allow simulation
22of chambers with overlapping modules (MakePadHits, Disintegration).
23
802a864d 24Revision 1.23 2000/06/28 12:19:17 morsch
25More consequent seperation of global input data services (AliMUONClusterInput singleton) and the
26cluster and hit reconstruction algorithms in AliMUONClusterFinderVS.
27AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction.
28It requires two cathode planes. Small modifications in the code will make it usable for
29one cathode plane and, hence, more general (for test beam data).
30AliMUONClusterFinder is now obsolete.
31
30aaba74 32Revision 1.22 2000/06/28 08:06:10 morsch
33Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the
34algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton.
35It also naturally takes care of the TMinuit instance.
