Notes.
Most likely mass value from the luminosity-Teff plane is given in parenthesis. All objects are assumed to be single.
Minimum detectable companion masses (see Sect. 5.5).
The lack of lithium in its atmosphere is not consistent with such young age and low mass (see Sect. 5.3). Surface gravity and minimum detectable companion masses are not computed for this object.
