Notes. The central-star masses are estimated by means of the post-AGB tracks of Miller Bertolami & Althaus (2006, and priv. comm.) used in Fig. 11. Central-star parameters are from (1) Morisset & Georgiev (2009), (2) Herald & Bianchi (2011), (3) Malkov (1997), (4) Georgiev et al. (2008), (5) Kudritzki et al. (2006), (6) Méndez et al. (1992), and (7) Miller et al. (2016). Luminosities are scaled to the new expansion distances, and the luminosity errors consider only the distance uncertainties.
