(E, L_z) diagrams Top left: GGCs considered in this work. OoI, OoII, and non-Oosterhoff-type GGCs are shown as filled circles, diamonds, and crosses, respectively. The GGCs are classified as either in situ or accreted according to Belokurov & Kravtsov (2024) and plotted in different colours (see labels). Bottom left: Same but according to the classification into eight progenitor types (Callingham et al. 2022). Each progenitor type is identified with a different colour in the figure (see the labels). Top right: Same as in the top-left panel but for the field RRLs. Bottom right: Same as in the bottom-left panel but for the field RRLs.
