Caption: Figure 3.

Position of PDS 144 N (top) with respect to PDS 144 S (bottom) over a 5 year baseline is seen in these HST images, and they show no change in separation. The schematic labeled UCAC3 shows the predicted location of the stars in our fourth epoch (MJD 55661) if we were to apply the UCAC3 proper motions to the two PDS 144 stars in our first epoch (MJD 53836).
