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."
See Andersen & Nordstroem (1983) for a detailed description of the
method employed throughout the entire observation program.

Note on RV:
Radial Velocity of the primary stellar component. Any secondary
components are indicated by a note in file "notes" (see Remarks field)
Note on o_RV:
Number of plates measured in determining the radial velocity and error
Note on RVvel:
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" varVel=1.75 is considered the lower
limit for possible variability in velocity, and varVel=2.5 the lower limit
for certain variability. See Andersen & Nordstroem (1983)
Note on RV(HK):
Velocity of interstellar H and K lines when measured separately
Note on RotClass:
The rotation class has the 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
Note on rem:
Remarks are indicated by one or more of the following "words":
REM Remark in file "notes"
