All objects are cool core clusters with a mass deposition rate different from zero (Peres et al. 1998).
Notes: a redshifts taken from the NASA Extragalactic Database; b Galactic photoelectric absorption extracted from the HEASARCH Database (LAB survey Kalberla et al. 2005); c net exposure times for the three EPIC instruments after data cleaning in ks; d extraction radius is half the cooling radius from Peres et al. (1998); e the two observations of Abell 4059 were merged before the spectral analysis.
