Apply cloud-top height corrections to eas_optical #78

Closed Areustle closed 1 year ago

Areustle commented 1 year ago

A long-standing feature planned for nuspacesim has been to employ a cloud-mask to the optical cherenkov calculation. In it's simplest form this would be a routine to eliminate optical photons generated from extensive airshower segments that occur below the top of atmospheric clouds in a given region of the planet, employing the simplifying assumption that any such occluded photons would not be visible to the detector.

Added logic for masking out generated photons from shower segments below cloud top height.

Added new CloudModel simulation class and two configuration types: MonoCloud and NoCloud.

Tested MonoCloud with 10km cloud top height, fixed cherenkov angle and photon density computations in the no-photon, and 1-segment cases.

Updated NssConfig and configuration XML to handle CloudModelTypes.

Be sure to add the cloud model type and selected parameters to the FITS header metadata.
