a–f Arranged according to the division in Fig. 1. The first row of the figure corresponds to the high-\({{{{\rm{z}}}}}_{\max }\) region, while the second row represents the low-\({{{{\rm{z}}}}}_{\max }\) region. From left to right, the columns depict the inner, local, and outer regions, respectively. As shown in Fig. 1a, high-\({{{{\rm{z}}}}}_{\max }\) refers to \({{{{\rm{z}}}}}_{\max } > \) 0.4 kpc, while low-\({{{{\rm{z}}}}}_{\max }\) indicates \({{{{\rm{z}}}}}_{\max } < \) 0.4 kpc. Inner represents Rguide < 7 kpc, local corresponds to 7 kpc < Rguide < 9 kpc, and outer refers to Rguide > 9 kpc. The numbers of stars in each bin are shown in the bottom-right corner of each panel. The black dashed lines represent the fitting result by local nonparametric regression. Source data are provided as a Source Data file.
