Hello Hugh,

thank you very much for your always very useful comments!!!

As you know, I am simulating an payload (ASIM) wihich hopefully will be at a Columbus external platform one day. This instrument (MXGS) has an aperture (576 cm2) on the bottom in order to detect Transient Gamma Flashes (TGFs) from the atmosphere and also for aurora studies.

The assumption of omni-directional radiation and cosine law in a sphere is perfect for isotropic shielded structures, like ISS, but in my case I don't have the same shielding in all the instrument due to the apperture but the instrument is pointing at nadir so it has the Earth natural shielding.

Therefore, I am looking for another more accurate solution which, as my poor knowledge, will be to have a half sphere shape. What do you think? Do you know any kind of solution?

Thanks again for you and all the people who is helping me.

Regards, Andres
