eclipsing binaries with known photometric or spectroscopic orbits.

ADC_Keywords: Binaries, orbits; Combined data ; Binaries, eclipsing
Abstract:
The catalog contains two parts: 96 well known semidetached eclipsing
binaries with known photometric and spectroscopic orbits (table1.dat),
and 136 semidetached eclipsing binaries with known photometrical
orbital elements and unknown spectroscopic orbit (table2.dat).

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 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').
