💡 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.
Almeida et al. (2025): Mass determination: intermediate fit. Isochrone match: good fit.
Hunt & Reffert (2024): Classified as a moving group.
Cavallo et al. (2024): Gold sample.
