Proper motions are taken from TGAS (Gaia Collaboration 2016a). Distances are taken from Astraatmadja & Bailer-Jones (2016) computed with TGAS parallaxes assuming a Milky Way prior. The assumed distance is the mode of the posteriors and the quoted 2σ uncertainties the difference between this value and the 5 and 95 percentile values, respectively.
