Distribution of the clusters published in the PSZ2 Planck catalogue (Planck Collaboration XXVII 2016) in the mass-redshift plane. The masses in the Planck catalogue were derived iteratively from the M₅₀₀–Y_SZ relation calibrated using hydrostatic masses from XMM-Newton; they were not corrected for the hydrostatic equilibrium bias. The magenta and green points represent the Tier 1 and Tier 2 clusters of the CHEX–MATE sample, respectively (CHEX-MATE Collaboration 2021). The triangles and squares identify the morphologically relaxed and disturbed clusters, respectively, which were identified according to the classification scheme in Campitiello et al. (2022). The two red crosses identify the clusters excluded from the analysis of this work.
