Data are analyzed for 775 stars selected from the Grid Giant Star Survey, spanning a wide range of effective temperatures (Teff), gravities, and metallicities. The spectra are used to determine these stellar parameters and to monitor radial velocity (RV) variability at the 100m/s level. Description: Spectroscopic observations of 434 stars in the northern subsample of GGSS candidates were conducted in the period from 2001 January to 2002 December. We made use of the 2.1m telescope at the McDonald Observatory and the Sandiford Cassegrain echelle spectrograph, which provides R=55000 resolution. File Summary:
