Left panel: 2D histogram of the number density of stars from the Gaia RVS disk sample (in a cylinder of 300 pc radius and ±300 pc height around the Sun) in the (VR, Vφ) plane defined on a [−200,200] kms−1 × [0,400] kms−1 grid, binned with (1 kms−1)2 bins, together with the locations of the different moving groups. Top right panel: Same distribution in the (Jφ, JR) plane (computed with AGAMA in the potential of Table 1 ) defined on a [0, 600] km s−1 kpc−1 × [200, 3000] km s−1 kpc−1 grid, binned with (3 × 2 km2 s−2 kpc−2) bins. Bottom right panel: Median radial velocity VR (x, y) as a function of the position in the Galactic plane for the full sample of 17 414 667 stars with |z| < 300 pc. The grid is defined as [4, 12] kpc × [−4, 4] kpc, binned with (125 pc)2 bins. The Galactic center is located at (x, y) = (0 kpc, 0 kpc), the Sun at (x, y) = (8.275 kpc, 0 kpc) is represented with a cross, and the sense of rotation of the Galaxy is anti-clockwise.
