Relation of a) the mean stellar metallicity as 〈Z〉_L and b) the mean stellar age, as log〈τ〉_L, vs the stellar mass as log M_*. Green squares are the results from Cano-Díaz et al. (2022), blue triangles for star-forming galaxies and blue crosses for passive galaxies are the results from this work, and the blue cross in the bottom left shows the mean error of this work in stellar mass, mean stellar age, and mean stellar metallicity.
