Scientific paper
We present mean radial velocities for 143 stars in Selected Area 57 at the north Galactic pole that are suitable for use as secondary velocity standards. The stars were drawn from a magnitude-limited sample and are mostly fainter than 11th magnitude in V. They span a wide range of effective temperatures and surface gravities and thus provide a suitable source of targets for observed templates. The mean radial velocities are based on at least 10 observations spanning at least 8200 days, and are accurate typically to 0.2 km s-1, with no obvious signs of variable velocity or composite spectra.
Some of the results presented here used observations made with the MMT, a joint facility of the Smithsonian Institution and the University of Arizona.
