// Storage container for ratio between higain and logain charge extraction
// calibration results of the whole camera.
//
// Individual pixels have to be cast when retrieved e.g.:
// MCalibrationHiLoPix &avpix = (MCalibrationHiLoPix&)(*fHiLoCam)[i]
// 
// The following "calibration" constants can be retrieved from each pixel:
// - GetHiLoRatio(): The mean signal ratio between high-gain and low-gain
// - GetHiLoRatioErr(): The Gauss sigma of histogrammed signal ratios
//
// Averaged values over one whole area index (e.g. inner or outer pixels for 
// the MAGIC camera), can be retrieved via: 
// MCalibrationHiLoPix &avpix = (MCalibrationHiLoPix&)fRelCam->GetAverageArea(i)
//
// Averaged values over one whole camera sector can be retrieved via: 
// MCalibrationHiLoPix &avpix = (MCalibrationHiLoPix&)fRelCam->GetAverageSector(i)
//
// Note the averageing has been done on an event-by-event basis. Resulting 
// Sigma's of the Gauss fit have been multiplied with the square root of the number 
// of involved pixels in order to make a direct comparison possible with the mean of 
// sigmas. 
//

// The calculated values (types of GetPixelContent) are:
// 
// Fitted values:
// ============== 
//
// 0: HiLo Ratio
// 1: Error of HiLo Ratio
// 2: Sigma of HiLo Ratio == Resolution 
// 3: Error of Sigma of HiLo Ratio
