Notes.
The entry ‘geometric distance’ in the distance catalogue of Bailer-Jones et al. (2021) was used, except for HD 123139 which is not in Gaia EDR3 and therefore not processed by Bailer-Jones et al. (2021). In that case, we used the HIPPARCOS parallax to estimate the distance. The uncertainties are 1σ.
The effective temperatures of the calibrators were estimated from the spectral type using Pickles (1998).
IRAS 08534−2405 is not in the JMMC Stellar Diameter Catalog (JSDC). The diameter was taken from getStar (https://apps.jmmc.fr/~sclws/getstar/).
