t-SNE projection for SGB stars in GALAH DR3. Colours correspond to each group found by t-SNE+HDBSCAN from GALAH data. Abundance ratios are also shown, with the same colour coding. Upper panels: cumulative age distribution for each group. Middle panels: mean azimuthal velocity (left axis squares) and mean dispersion in azimuthal velocity (right axis stars) for each group. Lower panels: mean vertical velocity (left axis squares) and mean dispersion in vertical velocity (right axis stars) for each group. The error bars in the right panels represent the 95% confidence interval of a bootstrap resampling.
