MARs of the stacked clusters of CIRS (the two orange circles at low redshift) and HeCS (the two orange circles at high redshift). The median MARs of the individual clusters from Fig. 15 are shown in green. The value close to each circle is the mass M₂₀₀ in units of h⁻¹ M_⊙. The blue squares with the shaded bands are from Fig. 5 and show the median MARs and their spreads of the simulated clusters estimated with the three-dimensional mass profiles.
