- CC3 0.75 High quality
- Clit 0.82 Well-studied
- Cdup 1.0 Unique
Overview
NGC 6530 is a very rich, very dense object of high C3 quality. Its parallax locates it at a relatively close distance, near the mid-plane. It is catalogued as a near-solar metallicity, very young cluster, but with a large variance across recent sources for the mass parameter (see Parameters). It is well-studied in the literature. Note: This object shares a significant percentage of members with a later 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.
