12 + log O/H computed by NEBULABAYES (12 + log O/H_Neb) versus the difference $\overline{d}$ between 12 + log O/H_Neb and the metallicities computed through the (from left to right) SF, COMP (AGN+SF), and AGN calibrators (12 + log O/H_Cal). These distributions have been smoothed by a 2D Gaussian kernel density estimate (KDE), where the black contours outline density curves and darker shades of pink indicate higher densities. ellow histograms on the top panel showcase the distribution of $\overline{d}$ along with the 16th and 84th percentiles (purple dotted lines) of the distributions. Values of 12 + log O/H_Neb and 12 + log O/H_Cal are consistent within the errors. Gray arrows point toward the value of the median error on 12 + log O/H_Neb (ϵ in top panels), which is outside the range of values shown in the x-axis. This indicates that ϵ is 3× higher than the maximum difference between 12 + log O/H_Cal and 12 + log O/H_Neb.
