Abstract:
The new data on the orbital elements, masses and luminosities have
been collected for 31 pre-contact binary systems of short-periodic
RS CVn type. The results of statistical treatment of the catalogue
data pursue the goal of an accurate definition of the properties
and evolutionary status of the given class systems. The ages of
pre-contact systems have been estimated by isochrone method. Numerous
comments and bibliographic references to the catalogue are accessible.

Note (1): In the square brackets SP2 computed from the known spectrum SP1
and the ratio J1/J2.
Note (2): Note on mass ratio of components is numbered as follows:
0 = if q is found from double-lined spectra;
1 = if q is found from photometrical light-curve;
2 = if q is found by the relation (M-L) with the using mass function
from single-lined spectrum.
Note (3): Absolute bolometric magnitudes are calculated by their
geometrical parameters, spectral and luminosity classes. We used
effective temperature scale of Popper, 1980ARA&A..18..115. 1980ARA&A..18..115.
Note (4): Weight characterizes the reliability of evaluation of
photometric and absolute elements in 10-ball scale (highly unreliable
elements have weight 0; elements, evaluated with reliability,
approaching to reliability of the evaluation of elements by exact
methods over their light curves and radial velocity curves have W=9.
For systems with certain meaning of SP1 the elements are defined more
certainly and they have weight essentially larger than systems with
uncertain component spectrum.
Note (5): We used evolution models of Maeder & Meynet, 1988A&AS...76..411M 1988A&AS...76..411M.
