Single stellar population PNLFs depending on the age and metallicity for the fiducial model using the nebular metallicity correction by Dopita et al. (1992) and with variations of the IFMR (colored). The IFMRs are from Miller Bertolami (2016), in black, and Cummings et al. (2018), El-Badry et al. (2018), Cunningham et al. (2024), and Hollands et al. (2024), in turquoise, magenta, red, and light blue, respectively. The structure of the grid and the amount of PNe sampled for each PNLF are the same as in Fig. 7. The dotted PNLFs are constructed from the intrinsic [O III] magnitudes and the solid PNLFs additionally take into account the circumnebular extinction from Jacoby & Ciardullo (2025) as described in Sect. 2.6.
