Clusters with > 50 counts plotted on PDFs combining the maximum likelihood scaling relation, selection function, and mass function. The clusters in four redshift bins are shown, plotting the concentration, c₅₀₀ (left), and scaled density, n_s, 0 (right). The images show the average maximum likelihood scaling relation combined with the selection function and mass function for the clusters in the redshift ranges, with the solid contour lines at difference levels of −2, −4, −6, −8, and −10 from the maximum. The dashed contour lines show the average selection function, at levels of 0.05, 0.2, 0.4, 0.6, 0.8, and 0.95.
