Distributions of membership probabilities of our individual groups (separate panels), calculated with our methodology. The distribution of the membership probabilities of every star is plotted in blue, and the true group members in orange. The first two panels depict the Disc and the total Halo. The total Halo is decomposed into individual structures and Ungrouped Halo. By construction, a star’s probabilities of belonging to the Disc or the total Halo sum to one, and the total Halo membership is then decomposed into belonging to structures or Ungrouped Halo.
