mirror_degraded_reflection

Telescope: LSTN-01

Description: Mirror degradation factor (wavelength independent). Applied to the mirror reflectivity of the primary mirror (note also the primary, secondary, and camera efficiency degradation factors). What matters typically is the overall product of the efficiencies. Breaking it down into mirror(s) and/or camera degradation only matters where BYPASS_OPTICS becomes involved. Then this parameter is actually interpreted as being for reflection on the primary mirror (would not be relevant for a flat-fielding light source directly illuminating the camera or illuminating it via reflection on the secondary mirror). The nightsky background in each pixel is also scaled by the same factor (even if the actual simulation bypasses optical ray-tracing). For wavelength-dependent degradation, the tables for reflectivity, window transmission, or light-cone efficiency need to be adapted.
