Outside of the innermost few degrees, we find that the radial profile of the excess is background-model dependent and poorly constrained. The spectrum of the excess emission is observed to extend upwards of 10 GeV outside $\\sim5^\\circ$ in radius, but cuts off steeply between 10--20 GeV only in the innermost few degrees.
