Notes. Column 1: cluster name; Col. 2: X-ray luminosity in the 0.1–2.4 keV band; Col. 3: cluster core radius; Col. 4: central density; Col. 5: β parameter; Col. 6: cluster mean temperature; Col. 7: radio emission. H = giant radio halo detected; Col. 8: dynamical state. CC = cool-core cluster, M = merging system, D = debated, see explanation below. If not specified, data are from Chen et al. (2006). Quantities have been corrected for the cosmological model assumed in this paper.

no cool core according to Chen et al. (2006), but the cluster is found to be in a relaxed state with a moderate cool core, by the analysis of Takahashi & Yamashita (2003),
