Relative number of extracted objects with respect to the density thresholds, n_outer for hop (top) and min_value for dendrogram (bottom). The dotted red line gives the number of structures extracted at a given threshold value relative to the number of objects from the vibes extraction. The dashed horizontal gray line shows N = N_ref. The dotted green and blue lines show the relative number of objects having respectively a nonzero intersection and intersection-over-union higher than 50% with a vibes object associated to the same density peak. The colored lines and intervals give the mean and deviation over three snapshots and several vibes parameters.
