Top: t-SNE latent space at a perplexity of p = 50. Stream stars from STREAMFINDER are shown as filled coloured points, and stream stars from S5 as open coloured points, GCs are open coloured squares, satellite galaxies are open coloured circles, halo substructures are filled coloured circles, and extra stream stars from the literature are star symbols, coloured according to the legend. Bottom: t-SNE latent space coloured by the selected groups, with the left panel showing the selection of the main groups, the middle panel showing the selection of the subgroups, and the right panel showing the selection of the stream-cluster progenitors. Each group, subgroup and stream-progenitor pair is labelled by its group number which corresponds to the groups listed in Tables 2, 3, and D.1.
