Abundance ratios for stars with ﹩\mathrm{log}g﹩ > 4.0 after applying our abundance corrections. Blue points are those stars with S/N ≥ 100, and orange have S/N < 100. In the left column of panels, we plot the ratio of [ϵ/Fe] vs. ﹩{T}_{\mathrm{eff}}﹩ to show any residual trends we may have after applying our abundance corrections. Lines mark the ±0.1 and ±0.2 dex regions for reference. In the right column, we then show the behavior of that ratio with respect to changing [Fe/H] with a line at zero for reference.
