Notes.
M200m is the mass within a sphere of radius r200m, which is the radius above which the mass density drops below 200× the mean mass density of the Universe. M200c is similar but measured within the radius where mass density drops below 200× the critical density, and M500c is the mass enclosed within the radius above which the density falls below 500 times the critical density. The relation between these masses depends on the cluster’s mass profile. For a Navarro-Frenk-White (NFW) profile with concentration parameter c = 5, M500c ≈ 0.7M200c (White 2001; Pierpaoli et al. 2003), M178c ≈ 1.04M200c, and M200m ≈ 1.2M200c.
Other masses were measured within the specified physical radii. All M200m and M200c SL masses were obtained by extrapolating the profile obtained in the constrained region.
