Notes: "Star Clusters", by Brent Archinal and Steven Hynes, lists in the Comments (in part) for both these objects: ... "DSFG. Probably not a cluster." ... However, the CDS lists both as Open (galactic) Clusters. Photographically, they do appear as clusters. "Star Clusters" lists Berkeley 4 as 4.0 arc minutes, and King 16 as 5.0 arc minutes
