(Left) Regions of interest for the spectral analysis (see Table 1) overplotted to the unsharp mask: moving outwards, sectorN and sectorS are divided into two regions (in and out); frontE is divided into two regions across the front; frontW-in indicates the circular region in front of the edge; frontW-inN and frontW-outN, ..., out4N are the regions across the front pointing to the north-west; frontW-inS and frontW-outS, ..., out4S are the regions pointing to south-west. (Right) Surface brightness profiles extracted from the exposure-corrected 0.5–2 keV image fixing the centre on the BCG. The angles that define the sectors are measured anti-clockwise from the positive X-axis (angle = 0°). The arrows indicate the positions of the two fronts where there is a sharp steepening of the gradient. At the bottom, the ratios between the surface brightness profiles extracted in sectors and the profile obtained from the remaining X-ray emission assumed to be more undisturbed are plotted.
