Distribution of central entropies K₀ (left) and outer slopes α (right) of the HIGHMz clusters. Plot bars are colour coded according to the median centroid shift w in each bin. Bottom panels are the cumulative distributions of the two histrograms. Blue and golden vertical lines mark the positions of the peaks identified with ACCEPT (Cavagnolo et al. 2009) and REXCESS (Pratt et al. 2010), respectively. The red dotted line on the right is the canonical slope value of 1.1.
