XMM-EPIC (0.5–2 keV) surface brightness profiles of the galaxy cluster A795 and the candidate galaxy group. Black points are the surface brightness measurements, while the green line represents the particle background. The lower panel shows the residuals from the best-fit model. Left panel: A795 profile fitted with a double β model. The best-fit parameters are reported in Table 2. Right panel: Surface brightness profile of the extended X-ray source 7.36′ northwest of A795, that we interpret as a candidate galaxy group at a similar redshift of A795 (see Sect. 3.2.2 and Fig. 3), fitted with a single β model. The best-fit parameters are reported in Table 2 (last row).
