a, b Colour-coded by birth radius Rbirth. c, d Colour-coded by the stellar number density. The blue solid lines represent the fitting result by local nonparametric regression, and the blud dashed lines (the fitting results for local disc at low-\({{{{\rm{z}}}}}_{\max }\) region, shown in Figs. 5e and 6e) are overplotted for comparison. Source data are provided as a Source Data file.
