SFR to M_⋆ − Z_g relation. Our best-model m₃ is compared to observational results from Andrews & Martini (2013) (upper panel) and Yates et al. (2012) (bottom panel). In both cases, the original metallicity bins were respected. Solid lines show the observational results. The colour scale represents the SFR bin. The circles with error bars, connected by dashed lines, correspond to the median trend of our models. Error bars are computed using the first and third quartile of the distribution. In the upper panel, the solid black line represents the median trend of the − M_⋆ − Z_g relation.
