Thermal and nonthermal SEDs of the four scenarios considered, S1–S4, in logarithmic scale, where a face-on inclination is assumed. S1 and S3 are shown in the left plot, whereas S2 and S4 are shown in the right plot. Dashed lines correspond to S1 (left) and S2 (right), solid lines correspond to S3 (left) and S4 (right). We plot the nonattenuated inverse Compton contributions in gray. The emission peak at high energies is ∼10³³ erg s⁻¹ for S1 and S2, and ∼10³⁴ erg s⁻¹ for S3 and S4. The gamma-ray absorption due to γγ annihilation is total for energies > 10 GeV.
