Inferred spatial origin within the Galactic plane for all program stars. The stars are arranged in the same order as in Table 1, that is, with decreasing ejection velocity starting from the top left panel. As in Fig. 1, the most likely plane-crossing point is marked by a black cross, and the shaded areas visualize the corresponding 1σ (light red) and 2σ (light blue) contours. Note the different scales: Circles centered at the GC (black plus sign) with radii of 1 kpc (dotted black line), 8.3 kpc (solar circle; dashed red line), and 25 kpc (solid blue line) are shown for reference, when appropriate. The current position of the Sun (red square) is also marked.
