22 : // Data structure to store gaintables of the online calibration in the OCDB
23 : // consisting of three classes:
24 : // AliTRDCalOnlineGainTable
25 : // AliTRDCalOnlineGainTableROC
26 : // AliTRDCalOnlineGainTableMCM
27 : //
28 : // AliTRDCalOnlineGainTable is the main class from which all stored data can be accessed.
29 : // The two sub-classes AliTRDCalOnlineGainTableROC and AliTRDCalOnlineGainTableMCM
30 : // contain the gaintables on ROC level and on the MCM level respectively.
31 : //
32 : // The online calibration is used to compensate gain deviations on the pad level.
33 : // For the offline reconstruction the online calibration has to be undone.
34 : // The corresponding gain correction factor that was used by the online gain filter can be accessed
35 : // via the functions AliTRDCalOnlineGainTable::GetGainCorrectionFactor(Int_t det, Int_t row, Int_t col)
36 : // and AliTRDCalOnlineGainTable::GetGainCorrectionFactor(Int_t sector, Int_t stack, Int_t layer, Int_t row, Int_t col).
37 : //
38 : // AliTRDCalOnlineGainTableROC is a class to allocate MCM Gain Tables
39 : // and to access all stored calibration values from the ROC level by indicating row and col
