Angular momentum (or guiding space) structure of the G3RV2 stars near the Galactic plane (|z|< 200 pc): number of stars (left), unsharp masking of the density distribution (centre), and the mean radial velocity (right). Bottom row: the same, but for stars outside the SNd (at a cylindrical distance beyond 1 kpc from the Sun). Coloured lines depict the angular momentum selections that were used in (X_g,Y_g) coordinates to identify overdensities in Khoperskov et al. (2020a). The hole in the density distribution (R_g ≈ 7.6 kpc) in the bottom left panel is shifted towards the Galactic centre because the SNd contains more stars from the inner regions.
