10// Data structure to store gaintables of the online calibration in the OCDB
11// consisting of three classes:
12// AliTRDCalOnlineGainTable
13// AliTRDCalOnlineGainTableROC
14// AliTRDCalOnlineGainTableMCM
15//
16// AliTRDCalOnlineGainTable is the main class from which all stored data can be accessed.
17// The two sub-classes AliTRDCalOnlineGainTableROC and AliTRDCalOnlineGainTableMCM
18// contain the gaintables on ROC level and on the MCM level respectively.
19//
20// The online calibration is used to compensate gain deviations on the pad level.
21// For the offline reconstruction the online calibration has to be undone.
22// The corresponding gain correction factor that was used by the online gain filter can be accessed
23// via the functions AliTRDCalOnlineGainTable::GetGainCorrectionFactor(Int_t det, Int_t row, Int_t col)
24// and AliTRDCalOnlineGainTable::GetGainCorrectionFactor(Int_t sector, Int_t stack, Int_t layer, Int_t row, Int_t col).
25//
26// With the class AliTRDCalOnlineGainTablesMCM all values used for the
27// online calibration can be set and accessed on the MCM/channel level
28//
