Ejection velocity (relative to the rotating Galactic disk) vs. galactocentric radius at plane intersection for all program stars except S5-HVS 1, which is beyond the ordinate scale. Error bars are 1σ confidence intervals. The identification numbers above the data points correspond to those in Table 1. The colors mark objects that could stem from the GC (red) or from the outer disk (blue), see Fig. A.1.
