Notes. Parameters in this table are the primary and the secondary component masses (M1, M2), the mass ratio M1/M2 (q), the primary and the secondary component radii (R1, R2), the primary and the secondary component temperatures (T1, T2), the inclination angle (i), the semi-major axis (a), the eccentricity of the system (e), the argument of periastron (ω), and the binary spectral classes that are taken from Kobulnicky et al. (2014). The temperature for the primary component was fixed according to the spectral class (Gray 2001).
