- CC3 0.62 Intermediate quality
- Clit 0.0 Rarely studied
- Cdup 0.32 Possibly duplicate
Overview
HSC 1284 is a sparse, loose object of intermediate C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane. It is catalogued as a near-solar metallicity cluster (see Parameters). It was recently reported in the literature. Warning: This is possibly a duplicate object, which shares a significant percentage of members with at least one previously reported entry. See table with shared members information.

💡 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.
