Notes. In this table, we state the [Fe/H], the metallicity of the star, [Ba/Fe] (a proxy for [Eu/Fe]), the Gaia equatorial coordinates ra and dec (epoch 2015.5), the proper motions pmra and pmdec (in mas), the line-of-sight velocity (in km s−1) measured by Gaia and measured on the UVES spectra (Gaia RVel and UVES RVel) with the corresponding errors, the Gaia DR2 parallax corrected by the zero-point offset, the error σπ and σπ/π, and finally the distances of the stars d (in kpc) deduced from the parallax. The stars were kept only when σπ/π <  0.20.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
