FoF 1970
(LP 1970)
- CN 0.0 Sparse
- Cdens 0.06 Very loose
- CC3 0.12 Very low quality
- Clit 0.0 Rarely studied
- Cdup 1.0 Unique
Overview
FoF 1970 is a sparse, very loose object of very low C3 quality. Its parallax locates it at a moderate distance, above the mid-plane. It is catalogued as a massive, near-solar metallicity, intermediate-age cluster (see Parameters). It is rarely studied in the literature. 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.

💡 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.
