Fig. B.1
Effect of metallicity on the [O iii]/[O ii] ratio obtained from photoionization models. The models are computed for a PopStar ionizing radiation field (age 1 Myr) and are ionization-bounded. Continuous lines join models of same metallicity, while dashed lines join models with same ionization parameter. The color code is given in the plot. The positions of the observational points for our samples (red for DR10, blue for DR7) are shown for comparison.
