Radial profiles observed in the southern (left) and western (right) sectors reported in Fig. 3. In each panel: Top: SB profile with the best-fit to the broken power-law model. The SB is expressed in units of counts px⁻² s⁻¹ , the radius is in units of kpc. The dashed lines show the upper and lower confidence bounds of the best-fit density ratios (corresponding to 1.32 for the Sector S and to 1.37 for the Sector W). Bottom: projected temperature (black) and de-projected pressure (red) profiles. The black dashed line indicates the position of the front determined by the broken power-law fit to the SB profile shown in the upper panels.
