//  MReportStarguider
//
// This is the class interpreting and storing the STARG-REPORT information.
//
// This is the place to get the azimuth-/zenith mispointing of the telescope
// given by the starguider-camera.
//
//
// Class Version 1:
// ----------------
//  + Double_t fDevAz;          // [arcmin]   azimuth mispointing
//  + Double_t fDevZd;          // [arcmin]   zenith  mispointing
//
//
// Class Version 2:
// ----------------
//  + Double_t fNominalZd;          // [deg] Nominal zenith distance
//  + Double_t fNominalAz;          // [deg] Nominal azimuth
//
//  + Float_t  fCameraCenterX;      // [CCD pix] PMT Camera center found
//  + Float_t  fCameraCenterY;      // [CCD pix] PMT Camera center found
//
//  + UInt_t   fNumIdentifiedStars; // Number of stars identified by starguider algorithm
//
//  + Double_t fSkyBrightness;      // [au] Sky Brightness as calcualted from the CCD image
//  + Double_t fMjd;                // Modified Julian Date matching the nominal position
