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

<p>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&nbsp;<a href="https://arxiv.org/abs/2004.04263">https://arxiv.org/abs/2004.04263</a>.&nbsp;DBSCAN_labels_APOGEE_DR16.npy contains only members of groups with more than 15 members and silhouette coefficients greater than 0.&nbsp;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&nbsp;columns are described at&nbsp;<a href="https://data.sdss.org/datamodel/files/APOGEE_ASTRONN/apogee_astronn.html">https://data.sdss.org/datamodel/files/APOGEE_ASTRONN/apogee_astronn.html</a>. There are two additional columns:&nbsp;CLUSTER_ID, and&nbsp;&nbsp;SILHOUETTE_COEFF, which are respectively the label and silhouette coefficient for each star.</p>
