Strong chemical tagging with APOGEE: 21 candidate star clusters that have dissolved across the Milky Way disc

Two files containing the chemically tagged abundances derived by astroNN from the Apache Point Observatory Galactic Evolution Experiment. The chemical tagging procedure is described in https://arxiv.org/abs/2004.04263. DBSCAN_labels_APOGEE_DR16.npy contains only members of groups with more than 15 members and silhouette coefficients greater than 0. DBSCAN_labels_APOGEE_DR16_all.npy contains labels for all stars in the quality controlled data set. The data are packaged as a numpy structured array. Most of the columns are described at https://data.sdss.org/datamodel/files/APOGEE_ASTRONN/apogee_astronn.html. There are two additional columns: CLUSTER_ID, and  SILHOUETTE_COEFF, which are respectively the label and silhouette coefficient for each star.
