\caption{Proper motions for the target objects derived from SuperCosmos and 2MASS positions 
with the epoch difference indicated. For typical positional errors $\sim$0.3~\arcsec, uncertainties on the proper 
motions are therefore $\sim$100~mas~yr$^{-1}$, for
$\Delta_{\rm epoch}$~=~4~yr.
Transverse velocities are derived using the distances
in Table~\ref{tab1} and the proper motion values, added in quadrature.\label{tab3}}
