Notes. JHK measurements are from 2MASS. (*)Spectral type by Esplin & Luhman (2019) differs by 0.5 subclasses or more in comparison with Herczeg & Hillenbrand (2014). (**)For spectral types later than M5, the temperature conversion by Herczeg & Hillenbrand (2014) is used. The extrapolation for M6 in Pecaut & Mamajek (2013) would deliver 3038 K. (***)Teff derived spectroscopically by Alencar et al. (2018). (****)The provided amplitude and ⟨V ⟩ were combined to derive a more representative Vmin.
