Note (1): Mass ratio is found spectroscopically from radial velocity semi-amplitude ratio q=K1/K2 in table1 (Orb='A') For systems in table2 (Orb='B'), the mass ratio between components is estimated according to Plavets & Kratohwillin, assuming that the subgiant component has filled completely its critical Roche lobe. Note (2): The orbital semi-major axis is estimated from the third Kepler law and assuming a circular orbit. Note (3): Index '1' always corresponds to more massive component. Note (4): For systems lacking spectroscopic orbits (table2, Orb='B'), the mass and radius of the primary component were estimated according to the "Mass-to-effective temperature" and "mass-to-radius" relations obtained by the authors for stars of V luminosity class having known spectroscopic orbits (stars in table1). Note (5): The absolute bolometric magnitudes are computed with the formula Mbol=42.31-5*log(R/R)-10*logTeff. The stellar effective temperatures Teff are from Popper (1980, Cat. V/63) and Harmanec (1988BAICz..39..329H). Note (6): Ratio surface brightness is derived from the formula J1/J2=1.157*(1/T1-1/T2), where T is evaluated in tens of thousands K (104K). Note (7): For systems lacking spectroscopic orbits (table2, Orb='B'), note that the reliability of orbital element determination is marked by weights (w) essentially lower than that of table1 (Orb='A').
