Overview

CWNU 1399 is a moderately populated, very dense object of high C3 quality. Its parallax locates it at a large distance, near the mid-plane, affected by high extinction. It is catalogued as a massive, near-solar metallicity, old cluster (see Parameters). It was recently reported in the literature.

💡 Note: The parameters are sometimes transformed from their original values to match the format of the columns shown here, see FAQ. The columns DAv, Bfr, BSS correspond to differential extinction, binary fraction, and blue stragglers, respectively. BSS values can be listed as fractions or integers.
(*): indicates that this parameter is assigned more than one value in the corresponding reference.
