A suggested model for the SED including a secondary electron contribution located at the shock position. The low and high state spectra as measured with Fermi-LAT are shown for comparison (Yeung & Horns 2020). The secondary electrons’ spectrum during average (high) state is a power-law with dn/dγ ∝ γ^−2.3 between γ₁ = 3 × 10⁹ and γ₂ = 7(18)×10⁹. The magnetic field in the region is chosen to be 85 μG. The total energy content of the electrons is 2(3)×10⁴² ergs. The dotted lines indicate the effect of absorption on the Galactic foreground emission (see also Appendix B).
