Overview
DBSB 19 is a rich, very dense object of high C3 quality. Its parallax locates it at a close distance, near the mid-plane, affected by moderate extinction. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the absorption and age parameters (see Parameters). It is rarely studied in the literature.
Note: This object shares a small percentage of members with a later reported entry. See table with shared members information.
