19 | // Gain calibration using tracks | |
20 | // | |
21 | // The main goal: | |
22 | // 1.) Inner TPC gain alignement - (parabolic) parameterization (inside of one sector) | |
23 | // 2.) Angular and z-position correction (parabolic) parameterization | |
24 | // 3.) Sector gain alignment | |
25 | // | |
26 | // Following histograms are accumulated | |
27 | // a.) Simple 1D histograms per chamber | |
28 | // b.) Profile histograms per chamber - local x dependence | |
29 | // c.) 2D Profile histograms - local x - fi dependence | |
30 | // | |
31 | // To get the gain map - the simple solution - use the histograms - is not enough | |
32 | // The resulting mean amplitude map depends strongly on the track topology | |
33 | // These dependence can be reduced, taking into account angular effect, and diffusion effect | |
34 | // Using proper fit modeles | |
35 | // | |
36 | // | |
37 | // | |

39 | // === Calibration class for gain calibration using tracks === | |
40 | // | |
41 | // 1) Genereal idea | |
42 | // ================ | |
43 | // A 6-parametric parabolic function | |
44 | // | |
45 | // G(x, y) = p0 + p1*x + p2*y + p3*x^2 + p4*y^2 + p5 * x*y | |
46 | // | |
47 | // is fitted to the maximum charge values or total charge values of | |
48 | // all the clusters contained in the tracks that are added to this | |
49 | // object. This fit is performed for each read out chamber, in fact even | |
50 | // for each type of pad sizes (thus for one segment, which consists of | |
51 | // an IROC and an OROC, there are three fitters used, corresponding to | |
52 | // the three pad sizes). The coordinate origin is at the center of the | |
53 | // particular pad size region on each ROC. | |
54 | // | |
55 | // Because of the Landau nature of the charge deposition we use | |
56 | // different "types" of fitters instead of one to minimize the effect | |
57 | // of the long Landau tail. The difference between the fitters is only | |
58 | // the charge value, that is put into them, i.e. the charge is subject | |
59 | // to a transformation. At this point we use three different fit types: | |
60 | // | |
61 | // a) simple: the charge is put in as it is | |
62 | // b) sqrt: the square root of the charge is put into the fitter | |
63 | // c) log: fgkM * Log(1+q/fgkM) is put into the fitter, with | |
64 | // q being the untransformed charge and fgkM=25 | |
65 | // | |
66 | // The results of the fits may be visualized and further used by | |
67 | // creating an AliTPCCalROC or AliTPCCalPad. You may specify to undo | |
68 | // the transformation and/or to normalize to the pad size. | |
69 | // | |
70 | // Not every track you add to this object is actually used for | |
71 | // calibration. There are some cuts and conditions to exclude bad | |
72 | // tracks, e.g. a pt cut to cut out tracks with too much charge | |
73 | // deposition or a cut on edge clusters which are not fully | |
74 | // registered and don't give a usable signal. | |
75 | // | |
76 | // 2) Interface / usage | |
77 | // ==================== | |
78 | // For each track to be added you need to call Process(). | |
79 | // This method expects an AliTPCseed, which contains the necessary | |
80 | // cluster information. At the moment of writing this information | |
81 | // is stored in an AliESDfriend corresponding to an AliESD. | |
82 | // You may also call AddTrack() if you don't want the cuts and | |
83 | // other quality conditions to kick in (thus forcing the object to | |
84 | // accept the track) or AddCluster() for adding single clusters. | |
85 | // Call one of the Evaluate functions to evaluate the fitter(s) and | |
86 | // to retrieve the fit parameters, erros and so on. You can also | |
87 | // do this later on by using the different Getters. | |
88 | // | |
89 | // The visualization methods CreateFitCalPad() and CreateFitCalROC() | |
90 | // are straight forward to use. | |
91 | // | |
92 | // Note: If you plan to write this object to a ROOT file, make sure | |
93 | // you evaluate all the fitters *before* writing, because due | |
94 | // to a bug in the fitter component writing fitters doesn't | |
95 | // work properly (yet). Be aware that you cannot re-evaluate | |
96 | // the fitters after loading this object from file. | |
97 | // (This will be gone for a new ROOT version > v5-17-05) | |
98 | // | |
684602c8 | 99 | // |
100 | // In order to debug some numerical algorithm all data data which are used for | |
101 | // fitters can be stored in the debug streamers. In case of fitting roblems the | |
102 | // errors and tendencies can be checked. | |
