We provide a catalog of physical parameters for 1074 stars that are based on a uniform set of high-quality spectral observations, a uniform spectral reduction procedure, and a uniform set of stellar evolutionary models.

Note (1): Best-estimate parameters are computed from the mode values of the derived probability distribution functions (PDFs). The best-estimate parameter is left blank if the mode value of a PDF is outside the given parameter range; e.g., if a star has an estimated age of 0 or 14Gyr, the best-estimate age is not listed in the table. Similarly, the lower/upper bound of the credible interval is left blank if it lies outside the given parameter range. Note (2): Corresponding to the secondary maximum in the derived posterior probability distribution function (PDF). Note (3): Measured from the stellar surface.
