Globular cluster sample in the angular momentum versus total energy plane. The symbols denote the affiliation to specific progenitor, as indicated in the legend: red triangles for Aleph, cyan circles for the bulge, purple triangles for Cetus, cyan triangles for the disc, yellow triangles for Elqui, red circles for Gaia-Enceladus-Sausage (GES), yellow circles for the Helmi Streams (HS), purple circles for the low energy group (low-E), green circles for the retrogrades (retro), blue circles for Sagittarius (Sag), green triangles for Typhon, and black circles for the unassociated clusters. The dashed line at L_z = 0 marks the division between prograde and retrograde sides.
