The ratios L(5007)/ [L(3726) + L(3729)]  are shown against L(4686)/L(Hβ). The predictions from a selection of our simulations (the two 0.605 M_⊙ sequences are from Paper IV) is compared with Local Group data taken from Richer (2006, references therein and priv. comm.). The Galactic bulge data are from Stasińska et al. (1998). Shown are only objects with well-determined line strengths and which are not fainter than two magnitudes below the [O iii] PNLF cut-off. Evolution proceeds from left to right and then down because of recombination. In order to be consistent with the data, the tracks are truncated at two magnitudes below the PNLF cut-off. The kinks seen in two sequences are due to the optically thick/thin transition.
