- CC3 0.75 High quality
- Clit 0.62 Moderately studied
- Cdup 1.0 Unique
Overview
Berkeley 100 is a rich, very dense object of high C3 quality. Its parallax locates it at a large* distance, above the mid-plane, affected by high extinction. It is catalogued as a near-solar metallicity, young cluster (see Parameters). It is moderately studied in the literature. (*): The parallax distance estimate (~6.08 kpc) differs significantly from the median photometric distance (~3.77 kpc).

💡 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.
