Left: CMD (top-right), and radial velocity distribution (top-left) of the RAVE stars in a 12 degree field centered on NGC 3201. The spatial distribution of the RAVE stars in a 5 degree field centered on the cluster is shown (bottom), and the King tidal radius of the cluster is shown by the large circle. The crosses (red in online version) show the RAVE stars whereas the triangles (blue in the online version) show the NGC 3201 stars studied by Côté et al. (1994). The circled RAVE stars are those for which a chemical analysis could be carried out. Right: [ Fe / H ], [ Si / Fe ] and [ Mg / Fe ] ratio of a subsample of these same stars for which abundances could be determined. The triangles (green in the online version) are the parameters of the NGC 3201 red giant stars obtained from intermediate-resolution spectra by Carretta et al. (2009) and high-resolution spectra by Muñoz et al. (2013).
