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 fits the histos. | |
24 | // The 2D histograms or vectors (first converted in 1D histos) will be fitted | |
25 | // if they have enough entries, otherwise the (default) value of the choosen database | |
26 | // will be put. For the relative gain calibration the resulted factors will be globally | |
27 | // normalized to the gain factors of the choosen database. It unables to precise | |
28 | // previous calibration procedure. | |
29 | // The function SetDebug enables the user to see: | |
30 | // _fDebug = 0: nothing, only the values are written in the tree if wanted | |
31 | // _fDebug = 1: a comparaison of the coefficients found and the default values | |
32 | // in the choosen database. | |
33 | // fCoef , histogram of the coefs as function of the calibration group number | |
34 | // fDelta , histogram of the relative difference of the coef with the default | |
35 | // value in the database as function of the calibration group number | |
36 | // fError , dirstribution of this relative difference | |
37 | // _fDebug = 2: only the fit of the choosen calibration group fFitVoir (SetFitVoir) | |
38 | // _fDebug = 3: The coefficients in the choosen detector fDet (SetDet) as function of the | |
39 | // pad row and col number | |
40 | // _fDebug = 4; The coeffcicients in the choosen detector fDet (SetDet) like in the 3 but with | |
41 | // also the comparaison histograms of the 1 for this detector | |
