Overview
HSC 1962 is a poorly populated, very dense object of very high C3 quality. Its parallax locates it at a moderate* distance, well above the mid-plane, affected by low extinction. It is catalogued as a metal-poor, old cluster, but with a large variance across recent sources for the metallicity parameter (see Parameters). It was recently reported in the literature.
(*): The parallax distance estimate (~4.96 kpc) differs significantly from the median photometric distance (~3.75 kpc).
Note: This object shares a large percentage of members with a later reported entry. See table with shared members information.
