Radial velocity measurements of a sample of northern metal-deficient stars 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 Swisstelescope at the Observatoire de Haute Provence during 1977-1986, arereported. The data are presented in extensive tables and graphs andcharacterized in detail. Seven stars are identified as spectroscopicbinaries, and their distribution as a function of period is shown to besimilar to that for a sample of metal-rich G stars. The present radialvelocities are found to be in relatively good agreement with those ofCarney and Latham (1987), but not with those of Stryker et al. (1985).
