Notes. ^(†)Heavily spotted source. T_eff, L_*, R_* and M_* values are estimated following the methodology described in Sect. 5.1.2.^(‡) Average uncertainties are 0.2 in log L_*, 0.3 in log R_* and 0.15 in log M_*. ^(a)Multiplicity: single (S), binary (B), tertiary (T), quadruple (Q). ^(b)Derived from the SpT-T_eff conversion of Herczeg & Hillenbrand (2014). ^(c)Subluminous YSO: the reported values are corrected for obscuration effects (See Sect. 4.3.1 of Alcalá et al. 2021). ^(d)Parameters derived in Alcalá et al. (2021).^(e) Value taken from APOGEE-2 DR16 (Jönsson et al. 2020).^(f)Estimated using GES and PALLA models. ^(g)Triple system: L_*, R_* and M_* taken from Schaefer et al. (2012) and scaled with the new Gaia EDR3 distance.
