Radial-velocity observations obtained over a five-year period with the McDonald Observatory photoelectric radial-velocity spectrometer are here reported for those stars not known to be velocity variable. There are 259 stars having 1650 observations included in the spectral type range F0 to M0 and brighter than V = 6.5 mag. For the best-observed 134 stars, the standard error of the mean velocity is typically better than ±0.9 km s -1 . Sixteen stars are shown to be constant to a sufficient level to warrant standard-star status. Six possible spectroscopic binaries are found.
