Mass–metallicity relation based on O3N2 (left), N2 (middle), and N2O2 (right) for z ∼ 0 and z ∼ 2.3 stacks, color-coded by SFR. Colored squares indicate the z ∼ 0 ﹩{M}_{* }﹩–SFR stacks of Andrews and Martini (2013). Colored stars with error bars show the z ∼ 2.3 ﹩{M}_{* }﹩–ΔsSFR stacks. Both samples are color-coded by SFR on the same scale. The red dashed line denotes the best-fit z ∼ 2.3 MZR for each line ratio, given in Table 2.
