Notes. Column 1: names of the sources as presented in Table 3. Columns 2, 4, and 6: measured [OIII]5007/Hβ, [OIII]5007/[NII]6584, and [NII]6584/Hα emission line ratios. Columns 3, 5, and 7: metallicity, parametrized by 12+log (O/H) implied by the ratios reported in Cols. 2, 4, and 6 respectively. We used Nagao et al. (2006) calibrations for [OIII]5007/Hβ, dust-corrected [OIII]5007/[NII]6584, and [NII]6584/Hα. We adopted the calibrations from Pettini & Pagel (2004) to infer [NII]6584/Hα (second row of 7th column) and O3N2 ([OIII]/Hβ / [NII]/Hα). Column 9: the value of 12+log (O/H) we adopted for our sources as a combination of the information coming from the more conclusive ratios. In the case of z3LAE2 we considered the higher branch of [OIII]5007/Hβ calibration the most representative of its metallicity, because EW(Hβ) was measured to be at least 10 Å (Hu et al. 2009).
