Notes. Columns are: redshift, mass, and Y_SZ parameter within R₅₀₀ (from the Planck cluster catalogue, PSZ2; Planck Collaboration XXVII 2016), radio power at 150 MHz as found by Botteon et al. (2023) (since for PSZ2G077.90−26.63 and PSZ2G107.10+65.32 the radio power was not reported or reported for different regions, we provide our estimate using the procedure described in Sect. 4.2.1), the light concentration ratio (c), centroid shift (w), and their combination (M) from Campitiello et al. (2022).
