The stellar radial velocity (RV) observations collected during the first eight years (1976–1984) of operation of the Fick Observatory photoelectric RV spectrometer have been tabulated for publication (Beavers and Eitter, 1986). Included are 16,000 observations of over 2,000 late-type stars. For these observations at the coudé focus of the 61 cm telescope the velocity zero-point is virtually the same as that for the early Lick radial velocity survey (Campbell and Moore, 1928), i.e. Lick-Fick = −0.08±0.08 km/sec. The zero-point comparison for DAO spectrometer measurements is DAO-Fick = −0.54±0.05 km/sec. During the last four years of this study the error of the “high quality dip” observations is ±0.8 km/sec. Thirty-three of these stars have been selected for use as future bright (m < 7.0) velocity standards at Fick Observatory.
