Spectral energy distribution for the best fit scenario (χ² = 7.5), which consists of an emitter with fast non-radiative losses and a weak (B = 0.5 G) magnetic field that is located at x = −1.2a and y = 0.8a. The normalization was set to reproduce an energy flux in the 0.1–10 GeV range equal to 2.8 × 10^-10 erg cm^-2 s^-1. Observational constraints in X-rays, MeV, GeV, and TeV energies are also presented.
