Observed relative motion for candidate companions observed at two epochs (blue circles). The red squares indicate the predicted position of the companion at the second epoch if it were a fixed background object based on the known proper motion of the primary (uncertainties compound proper motion uncertainty and first epoch position uncertainty). The first three panels present systems with adaptive optics imaging at two epochs while the last four make use of UKIDSS (UKIDSS 2, 7 and 10), or CFHT12K (CFHT 21) data as first epoch. Given the observing dates involved in this analysis, parallactic motion is negligible in these comparisons.
