Overview
CWNU 406 is a poorly populated, loose object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane, affected by low extinction. It is catalogued as a near-solar metallicity, intermediate-age cluster, but with a large variance across recent sources for the absorption, age, and metallicity parameters (see Parameters). It is poorly studied in the literature.
