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