Significance maps in the energy bands. The symbols and colours follow those of Figure 1, but for photon energies below 5 TeV (top left) and above (top middle). Significance maps derived with a larger smoothing kernel of 0.12° are shown in the bottom row. The map for photon energies above 5 TeV is repeated to show the contours from the two HAWC significance maps provided in Alfaro et al. (2024). Finally, the top right panel shows the size of the major axis in the “model A” fit for both H.E.S.S. (red points) and for the HAWC publicly available data (blue points). The dashed lines and shaded bands represent the best-fit size and uncertainty derived in larger energy ranges as presented in Table 1 and Alfaro et al. (2024). The error bars/bands represent the combined statistic and systematic uncertainty.
