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