Example of the mass-richness scaling, for redshifts in the range z_true = [0.5, 0.75] for all the cluster finders. The legend is the same as in Fig. 3. To improve statistics, the full detection catalogs, corresponding to true detections, were used to produce the figure. The original richness provided by the finders was renormalized for better comparison. Note that the richness provided by AMASCFI and sFoF are discrete, while it is continuous for the other codes.
