Fig. 3
Transmitted flux exp(− τγγ) as a function of the gamma-ray photon energy ϵ1, for the following viewing angle ψ = 0° (right), 30°, 60° and 90° (left). The disk has the same physical properties as in Fig. 2. Gamma-rays are injected at z = 100 Rin for illustrative purpose only. The Fermi-LAT energy band (100 MeV−10 GeV) is delimited by the dotted lines.
