Locations of the regions chosen for X-ray spectral modelling compared with the directions of the west rim, east shell, and south loop cloud complexes (same contours as in Fig. 7), displayed over the intensities obtained in the 0.25 (left) and 0.75 (right) keV bands after correcting for the Local Bubble and halo emissions (same as the bottom row of Fig. 7). The underexposed regions in the ROSAT survey are masked in white.
