Consensus matrix for the 3D groups found from 5000 MC iterations of HDBSCAN, using min_cluster_size = 3, min_samples = 3, and cluster_selection_method = excess of mass. Dark squares indicate groups with high pairwise comembership probabilities (P_ij), and Roman numerals indicate the associated Lupus subregions. Red labels indicate CTTSs that are marked as noise in more than 30% of the MC iterations, all of which are off-cloud sources.
