Notes. Spectrophotometric distances d, radial velocities vrad, and stellar ages τ are from Paper I (except for HVS 3, whose age and radial velocity are from Przybilla et al. 2008b). Proper motions μαcosδ, μδ, and their correlations (“Corr.” column) are from Gaia DR2. A suffix “(H)” in the “Object” column indicates that proper motions are from the HST. The quantities vGrf (current Galactic rest-frame velocity), vej, p (ejection velocity from the plane corrected for Galactic rotation), Pb (probability to be bound to the Galaxy), and τflight, p (flight time from the Galactic plane) result from trajectories calculated in Model I of Irrgang et al. (2013). More information on the trajectories is listed in Table A.1 and visualized in Figs. 3 and A.1. The given uncertainties are 1σ.
