From a principal component analysis, we find that the three-dimensional parameter space reduces to a Fundamental Plane in metallicity (FPZ) given by 12 + log (O/H) = -0.14 log (SFR) + 0.37 log (M<SUB>*</SUB>) + 4.82. The mean O/H FPZ residuals are small (0.16 dex) and consistent with trends found in smaller galaxy samples with more limited ranges in M<SUB>*</SUB>, SFR, and O/H. Importantly, the FPZ is found to be approximately redshift invariant within the uncertainties. In a companion paper, these results are interpreted with an updated version of the model presented by Dayal, Ferrara & Dunlop.STAMPAenArticle10.1093/mnras/stw19932-s2.0-85029527120000388122400067https://academic.oup.com/mnras/article/463/2/2002/28922442016MNRAS.463.2002HFIS/05 - ASTRONOMIA E ASTROFISICA
