Leptonic contribution to the SED of NGC 6611, considering two different ratio of electron-to-protons (K_ep) at injection. In the upper panel the case where no protons are injected is considered (labeled as K_ep ≫ 1), in the lower panel we consider the maximum allowed K_ep values that do not overshoot the data. The emission is described in terms of bremsstrahlung and inverse Compton. More details on the modeling can be found in the text.
