Projected phase-space diagram of the galaxies in the field of PSZ2 G044.20+48.66 (Abell 2142) and member selection. The distance D_c is the angular diamater distance to the cluster. This is the CHEX-MATE cluster with the greatest number of confirmed redshifts in the virialised region. The initial candidates within a radial distance of 3θ_{MMF3, 500c} from the X-ray peak, and within a window in velocity of ±Δ_{vrf, PSZ2} with Δ_{vrf, PSZ2} = 12 000 km s⁻¹ from the nominal PSZ2 estimate, are shown in orange. The virialised members (in blue) are selected within a radial distance of r_200c and a rest-frame velocity window of ±κσ_los(R), with κ = 2.7, where σ_los is the velocity dispersion along the line-of-sight at projected radius R. Radial distances are shown assuming the final cluster redshift.
