class AliTRDCalOnlineGainTableMCM: public TObject


 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

Function documentation

AliTRDCalOnlineGainTableMCM()

 constructor

~AliTRDCalOnlineGainTableMCM()

 destructor

Float_t GetGainCorrectionFactor(Int_t channel)

 returns the Gain Correction Factor of the given channel that was used by the online gain filter
 1.0 means no correction
 0.9 means a correction of -10%
 1.1 means a correction of +10% etc.

Short_t GetAdcdac()

 returns an integer between 0 and 31 which corresponds to an ADC reference voltage between 1.05V and 1.45V
 U_Ref =  (1.05V + (fAdcdac/31)*0.4V
 fAdcdac is the same value for all ADCs within one MCM

Float_t GetMCMGain()

 returns the Gain Factor which would lead to a Gain Correction Factor of 1.0
 this value is the same for all channels within one MCM
 this value is used for the online PID

Short_t GetFGAN(Int_t channel)

 returns the Gain Correction Filter Additive as an interger between 0 and 15
 as it is loaded into the TRAP

Short_t GetFGFN(Int_t channel)

 returns the Gain Correction Filter Factors as an interger between 0 and 511
 as it is loaded into the TRAP
