Abstract:
We derive the absolute physical and orbital parameters for a sample
of 18 detached eclipsing binaries from the All-Sky Automated Survey
(ASAS) data base based on the available photometry and our own radial
velocity (RV) measurements. The RVs are computed using spectra we
collected with the 3.9-m Anglo-Australian Telescope (AAT) and its
University College London Echelle Spectrograph (UCLES), and the 1.9-m
Radcliffe telescope and its Grating Instrument for Radiation Analysis
with a Fibre-Fed Echelle (GIRAFFE) at the South African Astronomical
Observatory (SAAO). In order to obtain as precise RVs as possible,
most of the systems were observed with an iodine cell available at the
AAT/UCLES and/or analysed using the two-dimensional cross-correlation
technique (TODCOR). The RVs were measured with TODCOR using synthetic
template spectra as references.

Note (1): Notes as follows:
a = Photometry is available from ASAS but the star is not indicated
as a variable
b = Star has a visual and/or physical companion
Note (2): The available distances are based on the Hipparcos parallaxes
(Perryman et al., 1997, Cat. I/239), except for V415 Aql (Brancewicz &
Dworak, 1980, Cat. II/150).
Note (3): The spectral type is based on Teff versus V-K relation for dwarfs
by Tokunaga (2000, in Cox A.N., ed., Allens' Astrophysical Quantities,
4th edn. Springer-Verlag, New York, p. 143).
