Notes. The spectral types derived in this work through spectral indices of Riddick et al. (2007) (RRL07), Jeffries et al. (2007) (J07), and Herczeg & Hillenbrand (2014) (HH14) are listed, as well as the adopted one. The stellar parameters derived include effective temperature (Teff), stellar luminosity (L*), stellar radius (R*), stellar mass (M*), age, veiling measured at 610 nm (r610 nm), and the observed Balmer jump (BJobs). For the Teff an error of 100 K is considered, and for the veiling measurements, the error is less than 0.2.
