Comparisons of the velocities above and below the Galactic plane. We plot the median azimuthal and vertical velocities (top) and velocity dispersions (computed as 1.5MAD values, bottom) for the whole sample AC20-ϖ∕σ_ϖ > 3 (black lines, not including the sample of RC with photometrically derived distances), and for stars with Z ≥ 0 (orange lines) and for Z < 0 stars (blue lines). Shaded areas represent the uncertainties. We observe notable asymmetries beyond 10–11 kpc.
