H.E.S.S. excess count rate maps for the on-peak (left panel) and off-peak (right panel) regions of the orbit. Theexcess is smoothed with the point-spread function of the instrument (68% containment radius of 0.06∘ , indicated by the grey circle) . The cross indicates the test position. Both plots have the same range, and the colour bar on the right-hand side is in units of excess counts per hour. The overlaid green contours represent 4, 5, and 6 σ statistical significance.
