XMM-Newton surface brightness maps in the 0.3-1.1 keV energy band, in units of counts/s/deg². Points sources are filtered out, and the maps, of 5″ pixel size, are adaptively smoothed with a 50 counts kernel and vignetting-corrected. Upper left panel: 0823030401 XMM-Newton pointing. Upper right panel: 0823031001 XMM-Newton pointing. Lower left panel: 0823030301 XMM-Newton pointing. The 0823031001 pointing is fully dominated by X-ray emission originating from the remnant, the 0823030401 pointing is only partially filled with X-ray emission, whereas the 0823030301 pointing is totally free of the remnant’s X-ray emission.
