[OIII]/[NII] as an abundance indicator at high redshift.

PETTINI M. and PAGEL B.E.J.

Abstract (from CDS):

Among `empirical' methods of estimating oxygen abundances in extragalactic Hii regions, the use of the ratio of nebular lines of [Oiii] and [Nii], first introduced by Alloin et al., is reappraised with modern calibration data and shown to have certain advantages over R23≡ ([Oii]+[Oiii])/Hβ and N 2 ≡[Nii]λ6583/Hα, particularly when applied to star-forming galaxies at high redshifts.
