MZR for ELGs in clusters at different redshifts. We show the galaxies from Cl0024 with errors in the determination of the metallicity below 0.3 dex and stellar masses over log(M/M_⊙) = 9.5 with filled black circles, the data from Maier et al. (2019) for the cluster XMMXCS J2215.9–1738 at z ∼ 1.5 with blue circles, the data from Tran et al. (2015) for XMM–LSS J02182–05102 at z ∼ 1.62 with magenta circles, and the data from Pérez-Martínez et al. (2023) for the cluster PKS 1138–262 at z ∼ 2.16 with orange circles.
