Scientific paper

Observations of 41 northern stars with Fe/H between -1.1 and -0.3, obtained with the Coravel radial-velocity scanner on the 1-m Swiss telescope at the Observatoire de Haute Provence during 1977-1986, are reported. The data are presented in extensive tables and graphs and characterized in detail. Seven stars are identified as spectroscopic binaries, and their distribution as a function of period is shown to be similar to that for a sample of metal-rich G stars. The present radial velocities are found to be in relatively good agreement with those of Carney and Latham (1987), but not with those of Stryker et al. (1985).
