25// MCalibrationPix
26//
27// Base Storage container for a calibration pixel. Holds mean and sigmas,
28// their errors, the fit probability and the number of pickup events for
29// the high-gain and the low-gain derived values.
30//
31// Errors are stored internally as variances, but are returned and filled
32// as square root of the variances.
33//
34// Calls to GetMean(), GetMeanErr(), GetSigma(), GetSigmaErr(), GetProb() or
35// GetNumPickup() and GetNumBlackout() test first the bit kHiGainSaturation
36// before returning the high-gain or low-gain value, analogue for the
37// corr. Setters.
38//
39// The three flags: kValid, kExcluded and kHiGainSaturation may be set.
40// The colors: kGREEN, kBLUE, kUV and kCT1 may be set.
