Notes. Column 1: HIPPARCOS identifier. Columns 2–4: main identifier, spectral type, and (spectroscopic) radial velocity (vr in km s−1) as given in SIMBAD. Column 5: estimated astrometric radial velocity (ρ) at epoch J2016.0 and its formal uncertainty (±σρ), both in km s−1. Column 6: goodness-of-fit in Eq. (2) for the estimated ρ (4 degrees of freedom).
