Left: redshift histogram of the ℒ_det > 15, ℒ_ext > 15 sample used in this work. Right: weak lensing calibrated total mass histogram of the ℒ_det > 15, ℒ_ext > 15 sample used in this work excluding upper limit measurements. Medians of the measurements are marked with dashed line. The overdensity radii of R₅₀₀ within which we measure the X-ray observables are calculated from these mass measurements (see Chiu et al. 2022).
