Photon count from the Fermi-LAT observation in the energy band 1−500 GeV. The angular resolution (68% containment radius) increases monotonically from ~1° to ~0.2° in the energy range 1−300 GeV (Ackermann et al. 2012). White contours follow the γ-ray emission. Black contours follow the NVSS 1.4 GHz emission (Fig. 2a). Markers and lines are as in Fig. 2a.
