Radial profiles: the shell model’s best-fit center point position (see Table 1) serves as a common center for the radial profiles of the γ-ray, X-ray, and radio data. Left panel: radial profile of the spatial distribution of the TeV γ-ray emission isshown as black crosses, which depict the measured TeV data points and their errors. The dashed red line corresponds to the radial profile of the sphere morphology and the green line to the shell model. Center and right panels: radial profiles in the TeV γ-ray, radio, 0.5–1 keV, and 2–5 keV X-ray regimes for different regions of RCW 86 are shown. While the center panel covers the entire position angle range, the right panel only shows the SW region with position angles between 190° and 230° (position angle 0° corresponds to north and 90° to east; see Fig. 1). Black crosses are measured VHE excess points. The low-energy (0.5–1 keV, dashed cyan line) and high-energy (2–5 keV, dotted brown line)X-ray band data and the radio data (solid magenta line) were smoothed with the H.E.S.S.-PSF to accountfor the different angular resolution of the different instruments. The radio data are from Molonglo Observatory Synthesis Telescope (MOST; see Whiteoak & Green 1996) and the X-ray data are from the XMM-Newton X-ray telescope (Broersen et al. 2014). The γ-ray and X-ray data are normalized so that the area underneath the curve is equal to one; the radio data are scaled such that the area underneath the data points is equal to 0.5.
