Abstract:
We present a uniform catalog of stellar properties for 1040 nearby F,
G, and K stars that have been observed by the Keck, Lick, and AAT
planet search programs. Fitting observed echelle spectra with
synthetic spectra yielded effective temperature, surface gravity,
metallicity, projected rotational velocity, and abundances of the
elements Na, Si, Ti, Fe, and Ni, for every star in the catalog.
Combining V-band photometry and Hipparcos parallaxes with a bolometric
correction based on the spectroscopic results yielded stellar
luminosity, radius, and mass. Interpolating Yonsei-Yale isochrones to
the luminosity, effective temperature, metallicity, and
α-element enhancement of each star yielded a theoretical mass,
radius, gravity, and age range for most stars in the catalog.

Global Notes:
Note (G1): Catalog sequence runs from 0 to 1040. Sequence number 0 is reserved
for the Sun. Future additions to this catalog will begin at sequence
number 1041. Designations for this catalog shall consist of the
acronym SPOCS, which stands for Spectroscopic Parameters of Cool
Stars, and a sequence number with leading zeros elided
(e.g., SPOCS 42).
