Relative movement of four point sources, in RA and Dec, for two observations of GSC 08350-01924. The black dotted line and black markers represent the motion one would expect from a background (BKG) source with respect to the primary, and the shaded area represents the error space. The dark blue marker represents a source showing no significant relative motion, consistent with a bound (BND) companion at 0.3″. The other coloured markers represent three background sources detected at separations of 10.5, 13.2 and 14.2″ from the primary.
