Cumulative number distributions of RGB stars for 1P (black line) and 2P (red line) as a function of distance scaled by R_hl for selected projected (2D) snapshots from 12 Gyr to 13.5 Gyr. 1P is more centrally concentrated than 2P only in the snapshot at 13 Gyr. The number distributions of both populations change significantly over time, and the overconcentration of 1P is a transient feature. The R_hl values, snapshot times, and the number of RGB stars are provided in the insets of each panel.
