Notes. The FMR parameters used in GALSBI-SPS are taken from the best-fitting values on GAMA galaxies in Bellstedt et al. (2021). We sampled the gas-phase oxygen abundance log(O/H) from a Normal distribution whose mean is given by the FMR. The coefficients of the SFR and stellar mass dependence in the FMR evolve with redshift (expressed in terms of look-back time), as well as the scatter σFMR(tlb) around the mean relation.
