Fig. A.1.

Intensity of the radiation emerging from a homogeneous, slab-like atmosphere with pure isotropic scattering at an angle of θ = 60°. The slab is illuminated by Iinc ∝ E−1 from the top and by black body radiation from the bottom, IBB(kTe) with kTe = 0.35 keV. The results are presented for two different total optical depths: τmax = 0.1 (left) and τmax = 100 (right).
