Notes. Results and statistical uncertainties (“Stat.”) are given as median values and 99% confidence limits which are derived via a Monte Carlo simulation. The Galactic coordinate system is introduced in Fig. 2. Disk-crossing quantities are labeled by the subscript “d”. The Galactic rest-frame velocity , the local Galactic escape velocity vesc, the Galactocentric radius r = (x2 + y2 + z2)1/2, the ejection velocity vej (defined as the Galactic rest-frame velocity relative to the rotating Galactic disk), and the flight time τflight are listed in addition to Cartesian positions and velocities. The probability Pb is the fraction of Monte Carlo runs for which the star is bound to the Milky Way.
