Notes. Column description: (1) BCG name; (2–3) J2000 equatorial coordinates; (4) spectroscopic redshift; (5) stellar mass from Burke et al. (2015, for RX 1532), from Liu et al. (2012, for MACS 1477), and from this work (for CHIPS 1911); (6) UV, Hα, [O II], and mid-IR based SFRs of RX 1532 (Fogarty et al. 2015), MACS 1447 (Liu et al. 2012), and CHIPS 1911 (Somboonpanyakul et al. 2021a), corrected for dust extinction; (7) specific SFR determined as sSFR = SFR/M_⋆; (8) sSFR for main sequence field galaxies with redshift and stellar mass of our targets estimated using the relation found by Speagle et al. (2014); (9) central entropy K₀ = k_BT_Xn_e^−2/3 of the cluster estimated using X-ray Chandra observations by Donahue et al. (2015) for RX 1532, Somboonpanyakul et al. (2021a) for CHIPS 1911, and Prasow-Émond et al. (2020) for MACS 1447.
