Description:
25,563 radial velocity measurements are reported for 1359 single-lined
stars in the Carney-Latham sample of 1464 stars selected for high
proper motion; for 171 of these, spectroscopic orbital
solutions are derived.
The radial velocities of nearly all of the 1464 stars defined in
Paper XII (J/AJ/107/2240) have been monitored with the CfA Digital
Speedometers (see Latham 1985, in IAU Colloq. 88, 21; and 1992, in IAU
Colloq. 135, 110). Three nearly identical instruments have been used
on the Multiple Mirror Telescope and 1.5 m Tillinghast Reflector at
the F.L. Whipple Observatory atop Mount Hopkins, Arizona, and on the
1.5m Wyeth Reflector located at the Oak Ridge Observatory in the town
of Harvard, Massachusetts. Echelle spectrographs have been used with
photon counting intensified Reticon detectors to record about
45Angstroems of spectrum in a single order. Most of the spectra were
centered near 5187Angstroems, but a significant number of the early
spectra were centered near 5197Angstroems. The shift in central
wavelength was adopted in order to include all three lines of the Mgb
triplet, after it was fully appreciated that all the other lines in
our spectral window became extremely weak for our most metal-poor
stars. The spectral resolution is about 8.5km.s-1 for all our
exposures, and the signal-to-noise ratios range from about 5 to 50 per
resolution element.

Note (2): On the native CfA system (0.139km/s should be added to
these velocities to put them on the absolute velocity system defined
by our observations of minor planets)
Note (3): From r2rvsao combined in quadrature with a floor error of 0.25km/s.
Note (4): Using Galactic V velocity and metallicity, as illustrated in Figure 7.
When either the Galactic V velocity or metallicity is unavailable,
this column is blank.

Note (5): Identified binary code:
SO = binary with robust orbit reported in table4.dat
