20// AliTRDCalibraFillHisto
21//
22// This class is for the TRD calibration of the relative gain factor, the drift velocity,
23// the time 0 and the pad response function. It fills histos or vectors.
24// It can be used for the calibration per chamber but also per group of pads and eventually per pad.
25// The user has to choose with the functions SetNz and SetNrphi the precision of the
26// calibration (see AliTRDCalibraMode).
27// 2D Histograms (Histo2d) or vectors (Vector2d), then converted in Trees, will be filled
28// from RAW DATA in a run or from reconstructed TRD tracks during the offline tracking
29// in the function "FollowBackProlongation" (AliTRDtracker)
30// Per default the functions to fill are off.
