//
// MSignalPix
//
// Storage container for the signal in a pixel in number of photons.
//
// NOTE: This container is NOT ment for I/O. Write it to a file on your
//       own risk!
//
// fIsSaturated: boolean variable set to kTRUE whenever one or more of
//               the low gain FADC slices of the pixel is in saturation.
//
// Version 2:
// ----------
//  - added fIsSaturated
//
// Version 4:
// ----------
//  - added fIsHGSaturated
//
// Version 5:
// ----------
//  - added fIdxIsland
//
// Version 6:
// ----------
//  - put the '!' into the comment line for
//      Bool_t   fIsCore;        //! the pixel is a Core pixel -> kTRUE
//      Short_t  fRing;          //! NT: number of analyzed rings around the core pixels, fRing>0 means: used, fRing= 0 means: unused, fRing= -1 means: unmapped (no possible to use in the calculation of the image parameters)
//      Short_t  fIdxIsland;     //! the pixel is a Core pixel -> kTRUE
//      Bool_t   fIsHGSaturated; //! the pixel's high gain is saturated
//    This is a queick hack to gain storage space - the structure of
//    the container for calibrated data will change soon.
//
// Version 7:
// ----------
//  - removed '!' from fRing to allow the status 'Unmapped' to be stored
//    after calibration (bad pixel treatment). This increases the file
//    size of the calibrated data by roughly 0.5%
