19 // Class for calibration of the cluster properties: //
20 // Cluster position resolution (RMS) and short term distortions (within pad or within time bin)
23 // 1. Creation of the residual/properties histograms
24 // 2. Filling of the histograms.
25 // 2.a Traklet fitting
26 // 2.b Resudual filling
27 // 3. Postprocessing: Creation of the tree with the mean values and RMS at different bins
28 // 4. : Paramaterization fitting.
29 // In old AliRoot the RMS paramterization was used to characterize cluster resolution
30 // Mean value /bias was neglected
31 // 5. To be implemented
32 // a.) lookup table for the distortion parmaterization - THn
33 // b.) Usage in the reconstruction
36 // 1. Creation of the histograms: MakeHistos()
38 // 6 n dimensional histograms are filled during the calibration:
39 // cluster performance bins
40 // 0 - variable of interest
41 // 1 - pad type - 0- IROC Short 1- OCROC medium 2 - OROC long pads
42 // 2 - drift length - drift length -0-1
43 // 3 - Qmax - Qmax - 2- 400
44 // 4 - cog - COG position - 0-1
45 // 5 - tan(phi) - local angle
47 // THnSparse *fHisDeltaY; // THnSparse - delta Y between the cluster and tracklet interpolation (+-X(5?) rows)
48 // THnSparse *fHisDeltaZ; // THnSparse - delta Z
49 // THnSparse *fHisRMSY; // THnSparse - rms Y
50 // THnSparse *fHisRMSZ; // THnSparse - rms Z
51 // THnSparse *fHisQmax; // THnSparse - qmax
52 // THnSparse *fHisQtot; // THnSparse - qtot
59 // The parameter 'clusterParam', a AliTPCClusterParam object //
60 // (needed for TPC cluster error and shape parameterization) //
62 // Normally you get this object out of the file 'TPCClusterParam.root' //
63 // In the parameter 'cuts' the cuts are specified, that decide //
64 // weather a track will be accepted for calibration or not. //
