Gaia-ESO Survey: The analysis of high-resolution UVES spectra of FGK-type stars?

(Affiliations can be found after the references) Received 2014; accepted 2014 Context. The Gaia-ESO Public Spectroscopic Survey is obtaining high-quality spectroscopic data for about 105 stars using FLAMES at the VLT. With the FLAMES-UVES link, high-resolution spectra are being collected for about 5 000 FGK-type stars. Aims. These UVES spectra are analyzed in parallel by several state-of-the-art methodologies. Our aim is to present how these analyses were implemented, to discuss their results, and to describe how a final recommended parameter scale is defined. We also discuss the precision (method-to-method dispersion) and accuracy (biases with respect to the reference values) of the final parameters
