Detected kinematic structures identified in this work.

Group	$\sqrt{J_{r}}$ $Mathematical equation: $\[\sqrt{J_{r}}\]$$ ± δ [kpc km s⁻¹]	L_z ± δ [kpc km s⁻¹]	Number of stars
Splash	16.0 ± 4.5	388 ± 300	3 071
GSE	35.0 ± 17.5	−130 ± 250	1 895
Thamnos1	13.5 ± 4.0	−600 ± 350	413
Thamnos2	8.6 ± 3.5	−1184 ± 175	29

Notes. Names of the structures are listed in Col. 1. Cols. 2 and 3 give the centres of the ellipses drawn around the kinematic structures, from which stars were selected for further analysis (see Fig. 2, panel d). The half widths and half heights of the ellipses (δ) are given in Cols. 2 and 3. Col. 4 provides the number of stars in each group.
