Received 2015 January 20; in original form 2014 November 26 ABSTRACT The study of stellar parameters of planet-hosting stars, such as metallicity and chemical abun- dances, 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 sam- ple 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.
