Fig. 4


Top: motion of DE065225 in the sky. North is up, east is left. Circles show the epoch-averaged measurements and the curve corresponds to the best-fit model of parallax and proper motion. The arrow represents the proper-motion vector and the dotted grid indicates the sky-projected pixels of FORS2 measuring 126 × 126 mas2. Bottom: the two panels show close-up views of epochs Nr. 2 and 7, where individual frame measurements are shown in grey and the epoch averages are shown in black with their mean uncertainties. A dashed line connects the epoch average to the model position.
