Top: MZR for the three cases in our toy model. We also plot our direct-T_e metallicity estimates. Bottom: Specific star formation rate (sSFR) as a function of gas-phase metallicity. We show sSFR vs. gas-phase metallicity for our Hγ stellar mass binned stacks. The error bars on the sSFR were calculated using the 16th and 84th percentile in the stacks. The top left and bottom left panels show Case 1 (‘normal FMR’). Our selection cut makes the MZR slope steeper. The top middle and bottom middle panels show Case 2 (‘no FMR’). Our selection cut does not affect the MZR slope. The top right and bottom middle panels show Case 3 (‘inverted FMR’). Our selection cut makes the MZR slope appear flatter. In all three cases, we find a negative correlation between sSFR and 12+log(O/H) upon implementing our selection cut.
