Spatial distribution of physical best-fit parameters across the SNR, overlaid on the H.E.S.S. gamma-ray significance contours at 3, 5, 7, and 9σ in black, red, orange, and green. For the leptonic model, colour codes are shown for the magnetic field strength (top left), exponential cut-off energies (top right), and particle indices (bottom left). For the hadronic models, only the particle indices (bottom right) are relevant and shown here. The 29 subregions labelled with grey numbers are boxes of side lengths 0.18° or 10.8 arcmin. To judge whether the differences region to region are significant, the statistical uncertainties listed in Tables 6 and 7 have to be taken into account, and ultimately the H.E.S.S. systematic measurement uncertainties discussed above as well. When doing this, the spectral indices show no variation across the SNR in either scenario.
