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).
