802a864d 17Revision 1.23 2000/06/28 12:19:17 morsch
18More consequent seperation of global input data services (AliMUONClusterInput singleton) and the
19cluster and hit reconstruction algorithms in AliMUONClusterFinderVS.
20AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction.
21It requires two cathode planes. Small modifications in the code will make it usable for
22one cathode plane and, hence, more general (for test beam data).
23AliMUONClusterFinder is now obsolete.
24
30aaba74 25Revision 1.22 2000/06/28 08:06:10 morsch
26Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the
27algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton.
28It also naturally takes care of the TMinuit instance.
