New version of combine_emissions
in branch oc/02-surface_emission
. The emission from metis['scope_surface_list']
is now only slightly larger than from metis['eso_combined_reflection']
and slightly lower than the straight sum of surface emissions.

The effect
SurfaceList
returns thermal emission that is too low. This is presumably due to an error inradiometry_utils.combine_emissions
. Consider the following (this is the five ELT mirrors):The straight sum of emissions is in the correct ball park (needs small correction for reflectivity < 1). The emission of a single surface is also correct (matches the value given by old SimMETIS).
I think that
combine_emissions
should not consider any etendue, solid angle or area at all (assuming that etendue is conserved along the beam and no emission from outside the beam has to be included).
