Comparison of fitted IC source fluxes with GALPROP model δ₁ =δ₂ = 0.5 (left) and the same template maps but shifted in latitude by +25° (right). The expected spectrum is shown as a black curve and the extracted fluxes with crosses. The insets show a representative template map, with the unshifted map as contours in the right inset. No excess is found for the shifted templates, consolidating the signal found from the Galactic plane.
