Notes. Nc is the number of clusters in the sample. NM and Nm are respectively the sum of the membership weights and the total number of members with M⋆ ≥ 109.5 M⊙ in the clusters that are part of the sample, at all radii (Col. 3) and in the radial range used for the dynamical analysis (Col. 5). fSF is the fraction of star-forming galaxies among the members in the 0.05 ≤ R ≤ r200 radial range, identified based on their U − V and V − J rest-frame colors (for more details see text and van der Burg et al. 2020). z and r200 are evaluated using NM-weighted averages of the corresponding quantities for the clusters that are part of the sample. M200 is derived from r200, given z (see footnote 1).
