Abstract:
    We have recently carried out spectral synthesis modeling to determine
    Teff, log(g), vsin(i), and [Fe/H] for 1040 FGK-type stars on the
    Keck, Lick, and Anglo-Australian Telescope planet search programs.
    This is the first time that a single, uniform spectroscopic analysis
    has been made for every star on a large Doppler planet search survey.
    We identify a subset of 850 stars that have Doppler observations
    sufficient to detect uniformly all planets with radial velocity
    semiamplitudes K>30m/s and orbital periods shorter than 4yr.
