Description:
   This catalog presents new radial velocity determinations, based on 20 A/mm
   coude plates, for 146 southern stars brighter than m(v) = 8.3.  Drawn
   from the catalog of uvby-beta photometry of southern A5-G0 stars by Olsen
   (1983), 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.

Note on HDsuffix:
  Component designation as listed in Jeffers et al. (1963) When bytes 1-6
  are blank, the data in this record refer to the previous object. 

Note on HJD:
  Heliocentric Julian date of the observation (-2,440,000) 

Note on weight:
  Weight flag. "*" indicates that the observation has been given half weight. 

Note on RotClass:
  Rotation class Single-digit integer indicating the "rotation class
  assigned from the measured line widths." The classes and corresponding
  limits in v sin i are as follows (km/s):
  class    v sin i
    --     -------
     0     < 15
     1     16 - 30

     4    101- 150
     5       > 150
  
Note on rem:
  The following abbreviations are used:
  C    Preliminary CORAVEL results differ from the results of this catalog
        by 4 km/s or more.
  REM  An additional remark concerning this object can be found in the
        second file.
  SB2  Double-lined binary (as indicated in the literature or by preliminary
        CORAVEL results)

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.
