Notes. In the table we list the names of the clusters, the coordinates of their X-ray peaks, the Galactic absorption N_H along the direction of each cluster (HI4PI Collaboration 2016), the cluster redshifts (Piffaretti et al. 2011), and also the M₅₀₀ and R₅₀₀ values presented in Sect. 3.4. We report the ID of the observations used for this study, and whether they are central or offset pointings of the clusters. We also provide the average exposure time t_exp of each observation after soft proton cleaning, weighting the exposure of the three cameras as t_exp = 0.25 × t_exp, MOS1 + 0.25 × t_exp, MOS2 + 0.5 × t_exp, pn. Finally, we also list the names of the regions extracted from each offset observation to estimate the XRB parameters (see Fig. 1). The south and west offset observations of A2589 are discarded as heavily contaminated by soft proton flares, while the south-east offset pointing of Hydra A is discarded due to the diffuse thermal emission from LEDA 87445 (see Sect. 3.1).
