Cartesian projection of the Galactic disc using StarHorse distances. From left to right the maps are colour coded according to VR (first panel), Vϕ (second panel), and VZ (last panel). Upper panels: same region studied in Bovy et al. (2019), while the lower panels: zoom into the innermost 5 kpc of the Galaxy (the grey circles illustrate the Galactocentric distances of 5, 10, and 15 kpc. To guide the eye, in the figures we draw an ellipse with an inclination of 20° in relation to the Sun–GC line, 4 kpc semi-major axis length, and 1 kpc semi-minor axis length.
