Visual comparison of the whole CHEX-MATE sample and the studied cluster sample. Top: Mass-redshift distribution of the CHEX-MATE clusters (grey) with highlighted in red the targets considered in this work, alongside Tier-1 (0.05 < z < 0.2; M₅₀₀ > 2 × 10¹⁴ M_⊙) and Tier-2 (z < 0.6; M₅₀₀ > 7.25 × 10¹⁴ M_⊙) sub-samples. Bottom: Same comparison as the top panel, but for the c − w plane. The dynamical classification is taken from C22, with up (down) triangles indicating objects with δ > 0° (< 0°), while the two dashed lines are the median value of the c and w parameters of CHEX-MATE.
