Top: KDE histograms and median abundances (in [dex], dashed lines) for all elements across the GSE and in situ clusters. Middle: original elemental abundances compared to Galactic chemical evolution models (Romano et al. 2010, 2019). The models are y-shifted to match the Hot Thick Disk baseline. Background stars are shown in gray, while colored points indicate cluster members. The black-edged symbols represent stars identified as GSE in D23 but not recovered in this work. Bottom: same as the middle panel, but utilizing GAT-reconstructed abundances.
