Abstract

We present results of a spectroscopic analysis of 366 G and K giant stars. For 112 stars this is the first spectroscopic analysis. The stars were selected for a radial velocity survey, which is currently carried out at Lick observatory, using the Coude Auxiliary Telescope in conjunction with the Hamilton Echelle spectrograph. For each star a high signal to noise spectrum is available, which is used for the present analysis. The Teff, logg and iron abundance are determined by imposing excitation and ionisation equilibrium through stellar models. The micro turbulence is obtained by requiring no dependence of Fe I against equivalent width. The rotational velocity is obtained from a comparison with data from Gray (1989ApJ...347.1021G) and the macro turbulence is derived using Gray (2005PASP..117..711G).
