Description:
Radial Velocities of Bright Southern Stars is the result of an effort
to determine radial velocities for those southern stars in the "Bright
Star Catalogue" with no previously published radial velocity. This
version of the catalog combines three lists of data published
separately during 1983-85, the first for B-type stars, the second for
late-type stars, and the last for A- and F-type stars. J. Andersen
notes the following in a 1987 private communication:
"In order to make the 1982 edition of the 'Bright Star Catalogue'
as complete as possible, preliminary or even incomplete data
for many stars in this catalogue were provided in advance of
publication. The present catalogue presents the final values,
which should supersede (not be averaged with!) those given in
the Bright Star Catalogue."
The method employed throughout the entire observation program is
described by Andersen & Nordstroem (1983A&A...122...23A 1983A&A...122...23A).

Note (3): Radial Velocity of the primary stellar component. Any secondary
components are indicated by a note in file "notes.dat" (see Remarks field)
Note (4): this parameter "measures the ratio between the observed
plate-to-plate scatter for a given star and the scatter expected for
a constant star measured with the same uncertainty". A value of 1.75
is considered the lower limit for possible variability in velocity,
and 2.5 the lower limit for certain variability.
See Andersen & Nordstroem (1983A&A...122...23A 1983A&A...122...23A)
Note (5): The rotation class has the following values:
0 = v.sin(i) < 15km/s
1 = 15 < v.sin(i) < 50km/s
2 = 50 < v.sin(i) < 100km/s
3 = 100 < v.sin(i) < 175km/s
4 = 175 < v.sin(i) < 250km/s
5 = v.sin(i) > 250km/s

History:
The machine-readable files corresponding to the tables of the three
papers were kindly given by the author (J. Andersen) to the CDS in 1984.
The 3 catalogs were numbered III/102, III/103, and III/104.
The three catalogs were merged into a single one at the Greenbelt
Astronomical Data Center (ADC) by Anne C. Raugh in September 1987,
and described in the ADC "Documentation for Machine-Readable Version".
Full JD observation dates have been inserted in the "obs" file, and
this ReadMe documentation was prepared by F. Ochsenbein and J. Lyu in
January 1997.
The files "ReadMe" and "notes.dat" were revisited in June 2016 at CDS
to add the bibcodes (Francois Ochsenbein)
