Fig. 7
Map of 12 + log (O / H) as obtained through the [S ii] and [N ii]-based method of Dopita et al. (2016). Only spaxels with S/N> 3 are shown. Image dimensions are 34′′ by 38′′ or 6.1 kpc by 6.8 kpc, similar to Fig. 5. Methods to estimate 12 + log (O / H) based on electron temperatures return values that are 0.1–0.2 dex higher.
