Description:
This catalog presents new radial velocity determinations, based on
2nm/mm Coude plates, for 146 southern stars brighter than m(v)=8.3.
Drawn from the catalog of uvby-β photometry of southern A5-G0
stars by Olsen (1983, Cat. II/90), the program stars are certain or
suspected Population II stars. One triple-lined and 10 double-lined
binaries have been detected, including HD 210737, for which a
preliminary orbit has been derived. Notes on spectral peculiarities
are given.
The catalog is in two files. The first file lists HD number,
heliocentric Julian date of observation, radial velocity with error
and number of lines observed for both the primary and secondary stars,
rotation class, and remarks for each observation. The second file
contains additional remarks to the data of the first file, sorted by
HD number.

Remarks and Modifications:
Radial Velocities of Bright Southern Stars. V. 146 Population II F Stars and
Related Stars (RVF) was kindly supplied to the Astronomical Data Center
(ADC), NASA Goddard Space Flight Center, by Dr. J. Andersen over BITNET in
September 1987, in a format very similar to that described above.
Observations and notes were broken into separate files, blank lines between
observations of different objects were removed from the first file, and
blank columns were removed in both files.
