Same image as in Fig. 1 (with identical features in terms of smoothing and point-source removal) depicting the intensity variation across the remnant. The ten distinct subregions selected for further spectral analysis are highlighted as black regions. The entire remnant’s spectrum was obtained from the large polygonal shape region formed when combining all ten individual subregions. White and red contours mark the positions of 0693270301 and 0693270401 XMM-Newton pointings (shown in Fig. 4), respectively.
