We show the hydrostatic masses versus the caustic masses for the 14 clusters in our sample with the highest Ngal values, both calculated at the hydrostatic R₅₀₀. We show RCC clusters as blue triangles and NRCC clusters as red circles. The solid black line shows the best fitting model, with the shaded region indicating the 1σ uncertainty. The 1:1 line is also plotted as a dashed black line.
