Notes. The columns list the (1) star ID, (2) probability of being unbound from the Milky Way (Pesc), (3) radial velocity (vlos), (4) total galactocentric velocity (vT), (5) vertical position relative to the Galactic plane (z), (6) minimum galactocentric distance reached in the past (rmin), (7) time when the star reached its minimum galactocentric distance (trmin), (8) time when the star crossed the Galactic plane (tz=0), and (9) classification based on the orbital properties. The classification labels indicate whether the stars are of hypothetical extragalactic origin, cross the Galactic plane, or remain within the disk without crossing it.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
