III/134 Radial Velocities of Bright Population II F Stars (Andersen+ 1985) ================================================================================ Radial Velocities of bright southern stars. V. 146 population II F stars and related objects Andersen J., Nordstroem B. =1985A&AS...62..355A ================================================================================ ADC_Keywords: Radial velocities; Stars, A-type; Stars, F-type; Stars, G-type; Stars, population II Keywords: radial velocities ; population II stars ; F stars 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-{beta} 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.

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. (08-Jan-1997, by C.-H. Joseph Lyu, Hughes STX/NASA) Bibcodes (in ReadMe and remarks file) were added at CDS (July 2016) Acknowledgments: The original ADC documentation by A.C. Raugh (1988) was used to create this ReadMe file. References: Andersen, J. 1987, private communication. Jeffers, H. M., van den Bos, W. H., and Greeby, F. M. 1963, Publ. Lick Obs., 21.
