Row-normalised conditional metallicity distribution for high-α stars across orbital circularities for our α-selection (top) and Chandra et al. (2024) α-selection (bottom). The high-α disc, in situ halo (hot high-α disc), and accreted components can be seen in both panels. However, the contamination from the accreted GES merger is stronger in the Chandra et al. (2024) α-selection than the α-selection proposed in this work.
