Notes. The first column gives the aperture within which the caustic and hydrostatic masses were calculated. For this column, R₅₀₀ refers to the hydrostatic R₅₀₀. The second column gives the subset for which the summary statistics are given, and the third column N_C gives the number of clusters in that subset. Columns 4, 5 and 6 give the summary statistics. The mean bias is given in column 4, the median ratio of masses is given in column 5, and the intrinsic scatter between the caustic and hydrostatic mass is given in column 6. See Sect. 3.3 for details on how these values were derived.
