Top: Globular clusters from the GSE selected subgroups plotted in Galactic coordinates. Middle: Kinematic parameter spaces E–L_z and J_r–J_z are shown in the left and right panels, respectively. Each square symbol represents one GC and the grey points show the rest of the dataset to give context to where these GC populations lie. Bottom: Kernel density estimation of [Fe/H] distributions for each GSE subgroup.
