Column-normalised histogram of star number density in the LZ − VZ plane in the Galactic outer disc. The region of interest is marked by solid white lines at LZ = [2200, 2400] kpc km s−1, and by dashed white lines at LZ = 2000 and 2600 kpc km s−1, marking the areas used for comparisons in Figs. 1, 11, and 13. Features mentioned in the text are also marked. The figure contains all stars in our sample with 175° < ϕ < 185°, 12 723 513 in total.
