Overview
FoF 1388 is a sparse, very loose object of low C3 quality. Its parallax locates it at a large* distance, above the mid-plane, affected by moderate extinction. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is rarely studied in the literature.
(*): The parallax distance estimate (~5.41 kpc) differs significantly from the median photometric distance (~3.73 kpc).
â ī¸ Warning: the low UTI value and no obvious signs of duplication (Cdup=1.0) indicate that this is quite probably an asterism, moving group, or artifact, and not a real open cluster.
