Table 3:

Parallax and proper motion results.

Source 		  $\pi$    $D_\pi$    $\mu_\alpha^{a,b}$    $\mu_\delta^b$
    (mas)    (kpc)    ( ${\rm mas~yr^{-1}}$)    ( ${\rm mas~yr^{-1}}$)
ON 1   $0.389\pm0.045$    $2.57^{\rm +0.34}_{-0.27}$    $-3.24\pm0.89$c    $-5.42\pm0.46$c

Notes. (a) The proper motion, $\mu_\alpha$, includes the factor $\cos(\delta)$; (b) the errors of the proper motion take the uncertainty resulting from an apparent nonzero movement between the background sources into account; (c) for the proper motion of ON 1, we took an average of the north and south components.
