Notes. From left to right, the diving mass between the low-mass and high-mass sub-samples is in each redshift bin M500 = 3.71 × 1014M, 4.81 × 1014M, and 5.68 × 1014M (in the U = no RH cases); M500 = 3.71 × 1014M, 4.81 × 1014M, and 5.54 × 1014M (in the U = RH cases). The main uncertainty for fRH(obs) is driven by the RH classification (upper vs. lower panel).
