Information

  • Readme–Important notes when using the SAGA database
  • Information and News on update history (Database covers almost all the paper published by early 2019. All the coordinate data (RA and Decl) for MW stars are available since September 21, 2018.)
  • Tutorial–Tutorial for the data retrieval system
  • Data in the SAGA database
      • Updated on December 8, 2019
      • We found a bug in the identifications for some of the stars in dwarf galaxies. New IDs have been reallocated for those had erroneous IDs. We apologize for inconvenience caused by the change of star IDs.
    • Text data in tsv format (all the records)
      • Version December 11, 2019
      • 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 the uncertainties and the 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 during the observations with the highest resolving power
        • 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 December 11, 2019
      • 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 the SAGA paper series IV for the definition of the priority parameter.
