Observational characteristics of our synthetic population in right ascension (RA), declination (Dec), and heliocentric distance (D). Upper panels: entire mass range (full sample) of runaway masses, lower panels: the same for the US 708-analogue sub-sample (reduced sample). The full distribution, the D-distribution (panel C1), is shown in orange in panel C2 for comparison. Relative positions of the Galactic centre (GC) and US 708 are given for reference. We note that in RA and Dec the sample is restricted to objects closer than 20 kpc. See Appendix D for an extended plot of the distance distribution (C1 and C2).
