    • Updated on Jan 20, 2026
  • Text data in tsv format (all the records)
    • Version Jan 20, 2026
    • Abundances are in units of [X/H] (including Li where we adopted A(Li) = 3.26) normalized by the solar abundances of Asplund et al. (2009).
    • d(X) and f(X) stands for uncertainties and upper limits for element X, respectively.
    • New columns: Facility, Resolution, SN, Solar Abundance
      • Facility: observational facilities used to take spectra
      • Resolution: the highest resolving power obtained to take spectra
      • SN: the range of signal-to-noise ratio obtained to take spectra
      • Solar Abundance: solar abundances adopted to derive [X/H] or log-e(X) in the original paper
  • Text data in tsv format (recommended data set)
    • Version April 7, 2026
      • Some stars in the database were not correctly identified as the same objects when assigned different identifiers. This issue has been resolved in the current version.
    • Abundances are in units of [X/H] (including Li where we adopted A(Li) = 3.26) normalized by the solar abundances of Asplund et al. (2009).
    • Recommended list of data, provided by one record for one star, following our priority parameter. See SAGA paper series IV for the definition of the priority parameter.
