Scientific paper

We report high-precision atmospheric parameters for 1907 stars in the N2K low-resolution spectroscopic survey, designed to identify metal-rich FGK dwarfs likely to harbor detectable planets. Of these stars, 284 are in the ideal temperature range for planet searches, Teff<=6000K, and have a 10% or greater probability of hosting planets based on their metallicities. This catalog contains measurements of [Fe/H] (sigma[Fe/H]=0.07dex), Teff(sigmaTeff=82K), and logg (sigmalogg_=0.13dex). Atmospheric parameters are derived from Lick index measurements, as described in Robinson et al. (2006, Cat. ). Lick indices are measured from spectra obtained with the GCAM spectrograph on the 2.1m telescope at KPNO.
