     55//   readout chain dividing the signal to noise of the incoming number of photons
     56//   (= sqrt(number photons)) by the signal to noise of the outgoing summed FADC slices
     57//   signal (= MCalibrationPix::GetMean() / MCalibrationChargePix::GetRSigma() )
     58//
     59// The following calibration constants can be retrieved directly from this class:
    3460//
    3561// - GetConversionFactorFFactor    ( Int_t idx, Float_t &mean, Float_t &err, Float_t &sigma );

    38 // - GetConversionFactorCombined   ( Int_t idx, Float_t &mean, Float_t &err, Float_t &sigma );
