Table 3:

Common proper motions with Hipparcos stars in mas/yr.

$\mu_{\alpha}\cos{\delta}$ $\mu_{\delta}$ $\varepsilon$
Hip 63510A -616.3 $\pm$ 1.5 -13.6 $\pm$ 1.0  
ULAS J1300+12 -596 $\pm$ 7 +1 $\pm$ 7 23
Hip 73786A -608.8 $\pm$ 2.7 -502.7 $\pm$ 3.6  
ULAS J1504+05 -614 $\pm$ 4 -496 $\pm$ 8 22

Notes. Proper motions from linear fitting of the positions given in Table 2. For Hipparcos primaries data are taken from van Leeuwen (2007). $\varepsilon$ are the expected errors (see text).
