Notes. We used Teff and log 𝑔 from GF21. We include stellar type from Simbad, but where this was not available, the object was placed on a Hertzsprung-Russell (HR) diagram to determine whether it is on the main-sequence or white dwarf cooling track. (a)Sits below the main sequence but far to the right of the white dwarf cooling track on an HR diagram.
