Notes. The tabulated metallicity errors are only the propagated measurement errors. To obtain the total uncertainty in the metallicity one needs to add quadratically a systematic error of 0.14 dex for O3N2 and 0.18 dex for N2 (Pettini & Pagel 2004).
Integrated, luminosity-weighted mean stellar age in the region, obtained by absorption features.
