The study of stellar parameters of planet-hosting stars, such as metallicityand chemical abundances, help us to understand the theory of planet formationand stellar evolution. Here, we present a catalogue of accurate stellaratmospheric parameters and iron abundances for a sample of 257 K and G fieldevolved stars that are being surveyed for planets using preciseradial--velocity measurements as part of the CORALIE programme to search forplanets around giants. The analysis was done using a set of high--resolutionand high--signal-to-noise Ultraviolet and Visible Echelle Spectrograph spectra.The stellar parameters were derived using Fe I and II ionization and excitationequilibrium methods. To take into account possible effects related to thechoice of the lines on the derived parameters, we used three different ironline-list sets in our analysis, and the results differ among themselves by asmall factor for most of stars. {For those stars with previous literatureparameter estimates, we found very good agreement with our own values.} In thepresent catalogue we are providing new precise spectroscopic measurements ofeffective temperature, surface gravity, microturbulence, and metallicity for190 stars for which it has not been found or published in previous articles.
