// MMcRunHeader
//
// Root storage container for the RUN MONTE CARLO HEADER information
//
// This the second version of this output class. Old root files, which have
// a previous version of this class, are still compatibles and can be used.
// But of course, you can no try to get infromatino in these old files about
// the new data members.
//
// The following data member have been introduced in this second version 
// and they do not exist in the previous one:
//
//  Float_t fMcRunNumber;      Run Number
//  UInt_t  fProductionSite;   code to know where the run was generated
//  Float_t fDateRunMMCs;      Date of the MMCs production
//  Float_t fDateRunCamera;    Date, when the Camera program is run.
//  Byte_t  fRawEvt;           RawEvt[Data,Hedaer] stored or not
//  Byte_t  fElecNoise;        Electronic Noise simulated or not
//  Byte_t  fStarFieldRotate;  Is the starfield rotation switched on (1) or
//                             off (0)
//  Float_t fCWaveLower;       Wavelength limits for the Cerenkov photons
//  Float_t fCWaveUpper;
//  UInt_t  fNumObsLev;        Observation levels
//  Float_t fHeightLev[10];
//  Float_t fSlopeSpec;        Spectral index
//
//  Third version:
//
//  Byte_t fOpticLinksNoise;   Flag to state if the optic noise is simualted or not
//
//
// Note: All the azimuth Phi angles in this and other MC classes follow
// the convention in the Corsika program (see Corsika manual). There, phi
// is the azimuth of the momentum vector of particles, and is measured
// from the north direction, anticlockwise (i.e, west is phi=90 degrees).
// When it refers to the telescope orientation, it is the azimuth of a 
// vector along the telescope axis, going from the camera to the mirror. 
// So, fTelesTheta=90, fTelesPhi = 0 means the telescope is pointing 
// horizontally towards South. For an explanation, see also TDAS 02-11.
