Seven IAU radial-velocity standards included in the "homogeneous" list proposed by Mayor and Maurice (1985) have been measured with a coudé spectrograph/CCD fed by an optical fiber on the Coudé Feed Telescope of the Kitt Peak National Observatory. The same stars were also measured by using conventional slit spectra. The fiber-fed results exhibit generally higher precision than the corresponding velocities from the slit exposures and do not show the systematic errors seen in the latter.
