Sketch of the orbits of the two sample runaway ON stars HD 14633 (IDs#2, 2a) and HD 201345 (IDs#5, 5a) in the Galactic potential. Galactic Cartesian coordinates XYZ are employed, with the origin shifted to the position of the Sun for better comparison with Fig. 10, adopting the galactocentric distance from the GRAVITY Collaboration (2019). Left panel: galactic plane projection. Right panel: meridional projection, p, is the galactocentric distance, with the Galactic mid-plane indicated by the dashed line. The current positions of the stars are indicated by black dots, the curves show the trajectory calculated backwards in time until the Galactic mid-plane was crossed.
