Difference between 12 + log O/H_AGN, P24 and the values obtained giving in input to NEBULABAYES the [O III]/[S II]and [N II]/[S II] ratios from MAPPINGSV models (Thomas et al. 2018a) with a peak energy in the AGN accretion disk of logE_peak = −1.25, −1.5, −1.75, and −2.0. The gas pressure is fixed to logP/k = 5, after checking that the results do not change as a function of this parameter. The grey shaded area covers the range ±0.1 dex, which is the uncertainty associated to the parameters estimates with NebulaBayes. The median difference, ⟨D⟩, and the standard deviation (±σ) of the distribution are reported in the legend.
