Notes. The table lists the z-component of angular momentum (Lz), eccentricity (e), galactic apocentre (Rapo), galactic pericentre (Rperi) and maximum vertical amplitude (zmax). The left-handed system for the Galactic velocity components is used here, where U is positive towards the Galactic Centre, V is in the direction of Galactic rotation and W is positive towards the North Galactic Pole. The last column shows the population classification as described in Philip Monai et al. (2024), where TH ≡ thin disk, TK ≡ thick disk, and H ≡ halo.
