// Force reading a corsika file even if the footer (RUNE-section) is missing
// by setting fForceMode to kTRUE or from the resource file by
//
//    ForceMode: Yes
//
//
// To switch off the simulation of the camera electronics, use:
//
//    Camera: Off
//
// Note, that the border of the camera and the propertied of the cones
// are still simulated (simply because it is fast). Furthermore, this
// switches off the trigger for the output, i.e. all data which deposits
// at least one photon in at least one pixel is written to the output file.
//
//
// In case of a pedestal or calibration run the artificial trigger can
// be "switched off" and the cosmics trrigger "switched on" by setting
// fForceTrigger to kTRUE or from the resource file by
//
//    ForceTrigger: Yes
