Left: [α/M] vs. [M/H] contour plots of the thin disc component (75 642 stars, blue), the dissipative collapse component (15 433 stars, red), and the accretion component (1400 stars, green). Right: galactocentric rotational velocities V_ϕ as a function of [M/H]. We only show stars with parallax errors lower than 20%, S/N >  40 and “n&o” RAVE classification. We estimated the gradients of V_ϕ vs. [Fe/H] in the thin disc component and in the dissipative collapse component and find good agreement with literature values, depsite our different selection criteria (see for example Kordopatis et al. 2011b; Lee et al. 2011).
