Notes.(★) Hβ flux measurement uncertain.(&) Only Hβ line flux measured; C(Hβ) = 0 assumed. Col. 7: (a) Oxygen abundance derived from Te([O III]) following the Amorín et al. (2015) relation; expected ±0.08 dex statistical error; (b) Oxygen abundance from the direct method; the abundance derived using (a) is also given in square brackets for comparison; (c) Oxygen abundance from R23 empirical calibration (Izotov et al. 2019; Williams et al. 2023); expected ±0.10 dex statistical error; (d) No oxygen abundance derived; only [O III] nebular line measured. P: primary EELG sample; E: extended EELG sample.
