Image of the H.E.S.S. γ-ray  excess centred on the Puppis A SNR. The excess was smoothed with a Gaussian kernel of width 0.06° corresponding to the H.E.S.S. angular resolution (68% containment radius) for this analysis (shown in the bottom left inset). The colour scale represents the excess counts per surface area of π(0.06°)². The circular analysis region of radius 0.38°, matching the Fermi-LAT best-fit morphological model, is shown as a dashed circle. The two hemispheres are separated by a dashed line along the north/south axis in celestial coordinates. The black contours represent the 1.4 GHz continuum emission (Castelletti et al. 2006) at the 5, 10, 20 and 50 mJy/beam levels. The yellow cross indicates the position of the BEK (Hwang et al. 2005).
