19 | Initialisation of some pointers | |
20 | ||
3f5cf0b3 | 21 | Revision 1.7 2000/12/21 22:14:38 morsch |
22 | Clean-up of coding rule violations. | |

6a9bc541 | 24 | Revision 1.6 2000/10/06 09:04:50 morsch |
25 | ||
26 | - Dummy z-arguments in GetPadI, SetHit, FirstPad replaced by real z-coordinate | |
27 | to make code work with slat chambers. | |
28 | ||
e357fc46 | 29 | Revision 1.5 2000/10/02 16:58:29 egangler |
30 | Cleaning of the code : | |
31 | -> coding conventions | |
32 | -> void Streamers | |
33 | -> some useless includes removed or replaced by "class" statement | |
34 | ||
ecfa008b | 35 | Revision 1.4 2000/07/03 11:54:57 morsch |
36 | AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER | |
37 | The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC. | |
38 | ||
a30a000f | 39 | Revision 1.3 2000/06/28 15:16:35 morsch |
40 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
41 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
42 | framework. The changes should have no side effects (mostly dummy arguments). | |
43 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
44 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
45 | ||
802a864d | 46 | Revision 1.2 2000/06/28 12:19:18 morsch |
47 | More consequent seperation of global input data services (AliMUONClusterInput singleton) and the | |
48 | cluster and hit reconstruction algorithms in AliMUONClusterFinderVS. | |
49 | AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction. | |
50 | It requires two cathode planes. Small modifications in the code will make it usable for | |
51 | one cathode plane and, hence, more general (for test beam data). | |
52 | AliMUONClusterFinder is now obsolete. | |
53 | ||
30aaba74 | 54 | Revision 1.1 2000/06/28 08:06:10 morsch |
55 | Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the | |
56 | algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton. | |
57 | It also naturally takes care of the TMinuit instance. | |
