Notes. The ‘Calc rad’ column gives the stellar radius in cm as calculated from the stellar effective temperature (T_eff) and luminosity (L_★) using Eq. (3). The conversion between the calculated radii in cm and calculated diameters in milliarcseconds are done using the distances given in Table 1, and vice versa for the diameters in arcseconds and observed radii in centimetres. The observed diameters are all based on K-band observations except for π¹ Gru, where the observations were carried out at 1.625 − 1.730 μm. See text for further details. 1: McDonald et al.
