ecfa008b | 18 | Revision 1.4 2000/07/03 11:54:57 morsch |
19 | AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER | |
20 | The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC. | |
21 | ||
a30a000f | 22 | Revision 1.3 2000/06/28 15:16:35 morsch |
23 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
24 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
25 | framework. The changes should have no side effects (mostly dummy arguments). | |
26 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
27 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
28 | ||
802a864d | 29 | Revision 1.2 2000/06/28 12:19:18 morsch |
30 | More consequent seperation of global input data services (AliMUONClusterInput singleton) and the | |
31 | cluster and hit reconstruction algorithms in AliMUONClusterFinderVS. | |
32 | AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction. | |
33 | It requires two cathode planes. Small modifications in the code will make it usable for | |
34 | one cathode plane and, hence, more general (for test beam data). | |
35 | AliMUONClusterFinder is now obsolete. | |
36 | ||
30aaba74 | 37 | Revision 1.1 2000/06/28 08:06:10 morsch |
38 | Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the | |
39 | algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton. | |
40 | It also naturally takes care of the TMinuit instance. | |
