From top to bottom: mean azimuthal velocity, radial, vertical and azimuthal velocity dispersion of stars, as a function of their [Mg/Fe] ratio. In each panel, the relations are given for bins in [Fe/H], as indicated in the legend in the top panel. The black curves show the corresponding relation, for the total sample not binned in [Fe/H]. The 1σ uncertainty in each relation (coloured, shaded regions) is estimated through 1000 bootstrapped realisations. In all panels, only bins containing more than ten stars are shown.
