+// 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
