V/64 Eighth Orbital Elements of Spectroscopic Binaries (Batten+ 1989)
================================================================================
Eighth catalogue of the orbital elements of spectroscopic binary systems.
Batten A.H., Flechter J.M., MacCarthy D.G.
<Publ. Dominion Astrophys. Obs. 17 (1989)>
=1989PDAO...17....1B

ADC_Keywords: Binaries, orbits ; Binaries, spectroscopic
Description:
The complete description of the catalogue, as well as the notes, is to
be found in the Publ. Dominion Astrophys. Obs. 17 (1989). The present
machine-readable version was transformed from the file provided by
A.H. Batten for easier computer readability. Compared to the printed
version, please note the following:
1) The four columns No. f(m) m.sin^3(i) a.sin(i)
are NOT included in the computer version.
No. (running number) is the line number of the main file
(from 1 to 1469)
f(m) (expressed in Solar Masses)
can be computed from the Fortran formula
1.0385E-7 * (1-e*e)**1.5 * K(1)**3 * P
a(*)sin i (expressed in km)
can be computed from the Fortran formula
13751 * sqrt(1-e*e) * K(*) * P
m(*)sin3i (expressed in Solar Masses)
can be computed from the Fortran formula
1.0385E-7 * (1-e*e)**1.5 * K(*) * (K(1)+K(2))**2 * P
The parameters are
K(*) = velocity amplitude of the components, expressed in km/s;
P = Period, expressed in days, sometimes in years;
e = eccentricity
2) The notes, which make the bulk of the printed catalogue
(pages 129-304), are NOT included.

Historical Notes:
* June 1991: the catalogue was copied from ftp anonymous at dao.nrc.ca
* January 1992: catalogue transformation and first documentation
made by Francois Ochsenbein, Centre de Donnees Astronomiques,
Strasbourg (France),
* 16-Apr-1996: Documentation standardized at CDS.
The position of entry #874 (2S1553-42) was corrected .
The declination of entry #1057 (HD 170000) was corrected.
* 20-Oct-1997: Thanks to a remark by Steve Drake
<drake@lheavx.gsfc.nasa.gov>, the spectral types of secondary (Sp2)
which were missing have been added.
