MCMC corner plots for the analysis of the scaling relation of concentration, c₅₀₀ (top left) and c_{80 − 800} (top right), and density, n_s, 0 (bottom left) and n₅₀ (bottom right). The contours contain 39.3, 67.5, 86.4, and 95% of the samples. The contours are shown for the analysis with evolution in mean and width, where the centre positions of the clusters are fitted for, the same but using the peak cluster positions, a scaling relation with no evolution in width, with the fitted centres, and the same but only using clusters with more than 100 counts instead of 50 counts.
