Substructures in the R- projection inthe anticentre direction. (a) Number counts in the R- plane in binsof size ΔR = 0.02 kpc and for all stars in the AC20-ϖ∕σ_ϖ > 3 sample. (b) Same but applying a substructure mask to highlight the ridges (see text). (c–e) Same as b but for different stellar types. We also plot: some ridges from Ramos et al. (2018) with coloured lines, the separation of the bimodality (black dotted line), and the median velocity (black dashed line in panel b). We see the ridges extending beyond their limits in DR2 and new ridges resolved here for the first time.
