05c39730 | 17 | Revision 1.19 2001/03/20 13:32:10 egangler |
18 | Code introduced to remove ghosts with the charge correlation between the 2 | |
19 | cathods. A chi2 is performed for the 2 possibilities. | |
20 | If one gets good chi2 (with respect to the fGhostChi2Cut parameter) and the | |
21 | other wrong chi2, the ambiguity is solved | |
22 | If both gets good or both bad chi2, no choice is made | |
23 | By default the fGhostChi2Cut parameter is set to solve about 70% of ghost | |
24 | problems with about 2% errors, with the current version of the code. | |
25 | ||
26 | Implementation : | |
27 | fGhostChi2Cut is in AliMUONClusterFinderVS, with setters and getters. | |
28 | a fDebugLevel was also introduced to switch off some of the output. | |
29 | When an ambiguity is detected and not solved, the fGhost word in | |
30 | AliMUONRawCluster is set to 1 or 2, depending whether both charge chi2 are | |
31 | good or bad. | |
32 | a DumpIndex method was also added in AliMUONRawCluster to produce a printout | |
33 | of digit indexes. | |
34 | ||
35 | User incidences : | |
36 | By default, the code makes ghost check. If you want previous behaviour, | |
37 | put in MUONrawclusters the value of SetGhostChi2Cut to infinity (1e.6) is | |
38 | sufficient. | |

ecfa008b | 76 | Revision 1.8 2000/07/03 11:54:57 morsch |
77 | AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER | |
78 | The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC. | |
79 | ||
a30a000f | 80 | Revision 1.7 2000/06/28 15:16:35 morsch |
81 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
82 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
83 | framework. The changes should have no side effects (mostly dummy arguments). | |
84 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
85 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
86 | ||
802a864d | 87 | Revision 1.6 2000/06/28 12:19:18 morsch |
88 | More consequent seperation of global input data services (AliMUONClusterInput singleton) and the | |
89 | cluster and hit reconstruction algorithms in AliMUONClusterFinderVS. | |
90 | AliMUONClusterFinderVS becomes the base class for clustering and hit reconstruction. | |
91 | It requires two cathode planes. Small modifications in the code will make it usable for | |
92 | one cathode plane and, hence, more general (for test beam data). | |
93 | AliMUONClusterFinder is now obsolete. | |
94 | ||
30aaba74 | 95 | Revision 1.5 2000/06/28 08:06:10 morsch |
96 | Avoid global variables in AliMUONClusterFinderVS by seperating the input data for the fit from the | |
97 | algorithmic part of the class. Input data resides inside the AliMUONClusterInput singleton. | |
98 | It also naturally takes care of the TMinuit instance. | |
99 | ||
9825400f | 100 | Revision 1.4 2000/06/27 16:18:47 gosset |
101 | Finally correct implementation of xm, ym, ixm, iym sizes | |
102 | when at least three local maxima on cathode 1 or on cathode 2 | |

112 | Most coding rule violations corrected. | |
113 | ||
114 | Revision 1.1.2.2 2000/02/15 08:33:52 morsch | |
115 | Error in calculation of contribution map for double clusters (Split method) corrected (A.M.) | |
116 | Error in determination of track list for double cluster (FillCluster method) corrected (A.M.) | |
117 | Revised and extended SplitByLocalMaxima method (Isabelle Chevrot): | |
118 | - For clusters with more than 2 maxima on one of the cathode planes all valid | |
119 | combinations of maxima on the two cathodes are preserved. The position of the maxima is | |
120 | taken as the hit position. | |
121 | - New FillCluster method with 2 arguments to find tracks associated to the clusters | |
122 | defined above added. (Method destinction by argument list not very elegant in this case, | |
123 | should be revides (A.M.) | |
124 | - Bug in if-statement to handle maximum 1 maximum per plane corrected | |
125 | - Two cluster per cathode but only 1 combination valid is handled. | |
126 | - More rigerous treatment of 1-2 and 2-1 combinations of maxima. | |
