Important notes when using the database

This page is to be updated soon.

Known problems (last update: 12 Nov., 2012)

  • Search with the criteria does not work well.
    • Data with upper limits are not treated properly.
    • When multiple measurements report abundances for a selected element and one of them satisfies a criterion, the object is nominated as a plot candidate. This is not good when one of the data is like an outlier that only satisfies the criterion.

  • The database retrieval system creates the figures using gnuplot version 4.2.2. Therefore, the script downloaded from the server works with this version or later (maybe incompatible with version 4.0 and 3.X).
  • Object has sometimes two or more identifiers. For example, “CS31062-012” has other object names, “G268-32” and “LP706-7”. The SAGA database uses one ID for one object. In this case, you cannot retrieve with the name neither “G268-32” nor “LP706-7” at the moment. In the database, the names of objects are used according to the following priority by the catalogue name.
    • CS > BS > HE > HD > BD > CD > DH > G > HIP
  • All the name registered in the database can be seen in
  • You can check the object IDs used in the database from the links in the list.
  • Abundance conversion between log-e, [X/H], and [X/Fe] is done by using solar chemical composition based on Photospheric abundances in Table 1 of Grevesse et al. (1996, ASPC, 99, 117), irrespective of adopted solar abundances in the original papers. This will be fixed soon (6, Aug. 2012).
