Notes. The parameters are the following: Porb, the orbital period of the system determined from a best-fit phase-folding of the RV or photometric data not accounting for apsidal motion; e, the eccentricity of the orbit; KP (respectively KS), the amplitude of the RV curve of the primary (respectively secondary) star; i, the orbital inclination; MP (respectively MS), the mass; RP (respectively RS), the radius, Teff, P (respectively Teff, S), the effective temperature; log gP (respectively log gS); the surface gravity; and log(Lbol, P/L⊙) (respectively log(Lbol, S/L⊙)), the luminosity of the primary (respectively secondary) star. Errors are indicated in parentheses in terms of the last digits and represent 1σ.
