//////////////////////////////////////////////////////////////////////////////
//
// MMcFadcHeader
//
// This class contains the MonteCarlo information
// of the FADC simulation for the current run.
// The information is saved only once, whatever the
// number of events is
//
// NOTE : meaning of fAmplFadc, fAmplFadcOuter changed in camera 0.7,
// 30/03/2004: before it was amplitude of (gaussian) pulse, now is
// integral of pulse (which may be gaussian or not).
//
// In camera 0.7, the meaning of fPedesSigmaHigh, fPedesSigmaLow changed:
// before it was the rms of the single FADC slice. Now we calculate the
// RMS of the distribution of the sum of 14 FADC slices. The value we set
// as fPedesSigmaHigh/Low is that RMS divided by sqrt(14). It can be seen
// that the fluctuations of the integrated pedestal, when adding n slices
// to obtain the pixel signal, with n>~6, is more or less well
// approximated by sqrt(n)*RMS(sum_14)slices)/sqrt(14).
//
// Version 5:
//   Added member fGainFluctuations
//
// Version 6:
//   Added member fNoiseGainFluctuations
//
// Version 7:
//   Derived class from MCamEvent
//
// Version 9:
//   Added member fElecNoiseFileName
