Velocity maps of the pP30-RV sample in the Galactocentric XY plane. They show medians of radial (V_R), azimuthal (V_ϕ), and vertical (V_Z) velocities from top to bottom. The bins have 0.2 kpc per side and only those containing ten or more stars are shown. Black lines show the Galactic longitude limits of the sample. Grey lines indicate Galactocentric radii from 5 to 12 kpc and azimuths from −15° to 30° with 5° steps.
