Abstract:
We report new photometry and radial velocities for almost 500 stars
from the Lowell Proper Motion Catalog. We combine these results with
our prior sample and rederive stellar temperatures based on the
photometry, reddening, metallicities (using Chi^2 matching of our
22,500 low S/N high resolution echelle spectra with a grid of
synthetic spectra), distances, space motions, and Galactic orbital
parameters for 1269 (kinematics) and 1261 (metallicity) of the 1464
stars in the complete survey. The frequency of spectroscopic binaries
for the metal-poor ([m/H]≤-1.2) stars with periods shorter than 3000
days is at least 15%. The spectroscopic binary frequency for
metal-rich stars ([m/H]>-0.5) appears to be lower, about 9%, but this
may be a selection effect. We also discuss special classes of stars,
including treatment of the double-lined spectroscopic binaries, and
identification of subgiants. Four possible new members of the class of
field blue stragglers are noted. We point out the detection of three
possible new white dwarfs, six broad-lined (binary) systems, and
discuss briefly the three already known nitrogen-rich halo dwarfs.

Lowell Proper Motion catalog since the author used their finding
charts. A few HD and BD names are used. RA and Dec: the positions were
taken directly from the observing catalogs used at the telescopes.
