Notes. Mstar is the total stellar mass, Rd the disc scale length, htz and htz the scale height at solar radius (8 ± 1 kpc) of respectively the thin and thick discs, and 〈Mst.part〉 the mean mass of the stellar particles. All parameters of the NIHAO-UHD galaxies are from Buck et al. (2020). For MW values: (a)Lian et al. (2025) (b)Bland-Hawthorn & Gerhard (2016).
