Scientific paper

In many cases the oxygen abundance can only be estimated using empirical methods such as R[23] (Pagel et al. 1979), S[23] (Vílchez & Esteban 1996) or S[234] (Oey & Shields 2000). But in face of the weak points and limitations of each R[23] and S[23(4)] methods, we understand that a more precise calibration with another method involving easily measurable lines, for a larger redshift range and with a monotonic low-dispersion relation, would be highly desirable.
