VLT/FLAMES LR v_los corrected for the shift created by the motion of the Sun around the Galactic centre at the position of Sculptor, colour-coded by [Fe/H], as a function of elliptical radius, r_ell (top) and the position along the major axis (bottom). The colour-code is blue stars: [Fe/H]<  − 2.5; black crosses −2.5 ≤ [Fe/H]<  − 1.5; and red circles [Fe/H]≥ − 1.5. Binned mean velocities are shown as steel blue points, with their standard deviation as bars.
