The ratio of the caustic masses (measured at the hydrostatic R₅₀₀) from Sohn et al. (2020) to those from Rines et al. (2013) are plotted as a function of the difference in Ngal between the analyses. The clusters are split into subsets containing those where the minimum Ngal used in the two analyses was at least 200 (green squares) and those where the minimum Ngal was less then 120 (red circles). The lines show the best fits to each subset.
