Notes. The last three columns give the radii and the effective temperatures as derived from self-consistent modelling and when considering the Gaia DR2 parallaxes, and the magnetic field strengths. Four targets have not been modelled yet. (*) For these two targets we keep the parallaxes from Hipparcos because of the binarity and/or the excessive brightness. (+) We report the average values of the effective temperatures and luminosities provided in Perraut et al. (2013).
