Fitting results in two bins of log₁₀(ν) = −1.55 (top panel) and −2.55 (bottom panel) for the BHB subsample of the smooth halo. In each panel, the orange points are BHB stars within the specified bin, while the green inverted triangles indicate the median value of r_gc. The black lines depict the best fitting results of the subsample. The blue points denote stars that were previously included in Figure 8 but have been excluded here due to their large residual of $\frac{\nu -{\nu }_{\text{fitting}}}{{\nu }_{\text{fitting}}}$ ≥ 0.6. In the top panel, the excluded BHB stars are responsible for the prominent overdensity in the solar neighborhood in Figure 7. In the bottom panel, these excluded stars are likely associated with the overdensity in the outer regions of the halo.
