// MHCalibrationChargeCam                                               
//
// Fills the extracted signals of MExtractedSignalCam into the MHCalibrationPix-classes 
// MHCalibrationChargeHiGainPix and MHCalibrationChargeLoGainPix for every:
//
// - Pixel, stored in the TObjArray's MHCalibrationCam::fHiGainArray and 
//   MHCalibrationCam::fLoGainArray
//
// - Average pixel per AREA index (e.g. inner and outer for the MAGIC camera), 
//   stored in the TObjArray's MHCalibrationCam::fAverageHiGainAreas and 
//   MHCalibrationCam::fAverageLoGainAreas
//
// - Average pixel per camera SECTOR (e.g. sectors 1-6 for the MAGIC camera), 
//   stored in the TObjArray's MHCalibrationCam::fAverageHiGainSectors and 
//   MHCalibrationCam::fAverageLoGainSectors
// 
// Every signal is taken from MExtractedSignalCam and filled into a histogram and 
// an array, in order to perform a Fourier analysis (see MHGausEvents). 
// The signals are moreover averaged on an event-by-event basis and written into 
// the corresponding average pixels.
//
// Additionally, the (FADC slice) position of the maximum is stored in an Absolute 
// Arrival Time histogram. This histogram serves for a rough cross-check if the 
// signal does not lie at or outside the edges of the extraction window. 
//
// The Charge histograms are fitted to a Gaussian, mean and sigma with its errors 
// and the fit probability are extracted. If none of these values are NaN's and 
// if the probability is bigger than MHGausEvents::fProbLimit (default: 0.5%), 
// the fit is declared valid.
// Otherwise, the fit is repeated within ranges of the previous mean 
// +- MHCalibrationPix::fPickupLimit (default: 5) sigma (see MHCalibrationPix::RepeatFit())
// In case this does not make the fit valid, the histogram means and RMS's are 
// taken directly (see MHCalibrationPix::BypassFit()) and the following flags are set:
// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kHiGainNotFitted ) or  
// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kLoGainNotFitted ) and 
// - MBadPixelsPix::SetUnsuitable(   MBadPixelsPix::kUnreliableRun   ) 
// 
// Outliers of more than MHCalibrationPix::fPickupLimit (default: 5) sigmas 
// from the mean are counted as Pickup events (stored in MHCalibrationPix::fPickup) 
//
// Unless more than fNumHiGainSaturationLimit (default: 1%) of the overall FADC 
// slices show saturation, the following flag is set:
// - MCalibrationChargePix::SetHiGainSaturation();
// In that case, the calibration constants are derived from the low-gain results.
//
// If more than fNumLoGainSaturationLimit (default: 1%) of the overall 
// low-gain FADC slices saturate, the following flags are set:
// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kLoGainSaturation ) and
// - MBadPixelsPix::SetUnsuitable(   MBadPixelsPix::kUnsuitableRun    )
// 
// The class also fills arrays with the signal vs. event number, creates a fourier 
// spectrum and investigates if the projected fourier components follow an exponential 
// distribution. In case that the probability of the exponential fit is less than 
// MHGausEvents::fProbLimit (default: 0.5%), the following flags are set:
// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kHiGainOscillating ) or
// - MBadPixelsPix::SetUncalibrated( MBadPixelsPix::kLoGainOscillating ) and
// - MBadPixelsPix::SetUnsuitable(   MBadPixelsPix::kUnreliableRun     )
// 
// This same procedure is performed for the average pixels.
//
// The following results are written into MCalibrationChargeCam:
//
// - MCalibrationPix::SetHiGainSaturation() 
// - MCalibrationPix::SetHiGainMean()
// - MCalibrationPix::SetHiGainMeanErr()
// - MCalibrationPix::SetHiGainSigma()
// - MCalibrationPix::SetHiGainSigmaErr()
// - MCalibrationPix::SetHiGainProb()
// - MCalibrationPix::SetHiGainNumPickup()
//
// - MCalibrationPix::SetLoGainMean()
// - MCalibrationPix::SetLoGainMeanErr()
// - MCalibrationPix::SetLoGainSigma()
// - MCalibrationPix::SetLoGainSigmaErr()
// - MCalibrationPix::SetLoGainProb()
// - MCalibrationPix::SetLoGainNumPickup()
//
// - MCalibrationChargePix::SetAbsTimeMean()
// - MCalibrationChargePix::SetAbsTimeRms()
//
// For all averaged areas, the fitted sigma is multiplied with the square root of 
// the number involved pixels in order to be able to compare it to the average of 
// sigmas in the camera.
