We are working to homogenize the database by revisiting the compilation process. The abundance data depend on various factors, such as stellar spectra, observations, and abundance analyses, which include model atmospheres and line lists. Since 2020, with the support of Dr. Patrick Francois, we have been compiling information on the adopted model atmospheres and more comprehensive data on the chosen solar abundances. This work is ongoing and will be detailed in an upcoming paper.

Adopted solar abundances
This is the list of adopted solar abundances when the compiled data are converted to abundances in units of [X/Fe], [X/H], or log-e(X).
The original data are converted to log-e(X) first to get a list of abundance data independent of adopted solar abundances. If the original data provides the data in [X/Fe] and adopted solar abundances, we use the reference solar abundance data below unless the values are specified in the original paper.
Here we list three sets of solar abundances, although there are large variety in the adopted solar abundances in the original papers.
Please note that these data sets are used when we search and plot the data in the data retrieval system.
Asplund et al. (2009, ARAA, 47, 481, 2009)
The data are taken from Table 1. We employed photospheric abundances for most element species, but we sometimes use meteoritic abundances for some elements.

Known problems
- downloading data in text format
- Retrieved data can be downloaded in text format. However, not all the data are provided. Note that only one datum is available for specified elements, for example, only [Fe I/H] appears in the data even if [Fe II/H] is also available. We are planning to include all the available data in the database, together with other specified quantities and coordinates.
- popup windows on the plot panels.
- There are minor problems in popup windows when the data are plotted using the data retrieval subsystem. The popup windows provide information on data and references, but references are not displayed for Milky Way stars. This problem will be fixed in the future update.
- time to plot data
- In the current version, it takes long time to plot data using the data retrieval subsystem. In particular, the time to plot figures is unexpectedly long when the replot button is pressed. We expect to reduce time for this process.
- radial velocities (RV)
- The RV data are available for only one record for each object in each paper. We have all the records of RV monitoring for individual objects in the database, but we provide only the first record of monitoring through the web site for a technical reason. We are planning to fix this problem in future updates.
- solar abundances
- We have taken into account the difference in adopted solar abundances, but not all the papers provide information on them. In such cases, we use Grevesse et al. (1996) as reference solar abundances. The list of data without the information on solar abundances will be uploaded later.

Important notes when using the database
-
The database retrieval system creates the figures using gnuplot version 4.2.6. 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 search with the object name neither “G268-32” nor “LP706-7” in the data retrieval subsystem. 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 the adopted solar abundances in the literature. If they are not available, we use photospheric abundances in Table 1 of Grevesse et al. (1996, ASPC, 99, 117).

C-rich : [C/Fe] ≥ 0.7 RGB : Teff ≤ 6000 and log g ≤ 3.5 EMP : [Fe/H] ≤ -2.5 CEMP-s : C-rich and EMP and [Ba/Fe] ≥ 0.5 CEMP-no : C-rich and EMP and [Ba/Fe] < 0.5
Data plot
-
A-1: Plotted data are automatically classified into categories according to the following criteria.
-
EMP: stars with [Fe/H] ≤ -2.5. Although the value of [Fe/H] depends on the observations, it is simply taken from the data in the most recent published paper, the largest resolution for observing set ups, and the smallest error bars. Fe I is preferably adopted for identical paper.
-
C-rich: stars with [C/Fe] ≥ 0.7. The selection condition of the data is the same as for EMP. “CEMP” means “C-rich” and “EMP”.
-
RGB: stars with Teff ≤ 6000 K and log g ≤ 3.5. Otherwise, the star is classified as “MS”.
- CEMP-s: stars that satisfy C-rich and EMP criteria and [Ba/Fe] ≥ 0.5.
- CEMP-no: stars that satisfy C-rich and EMP criteria and [Ba/Fe] < 0.5.

- Legends in the plot list have been changed.
- August 7, 2017
- Bug fix: data selection criteria did not work properly. This is a similar bug fix as in May 24, 2017. We may have uncovered the bug at some point.
- June 26, 2017
- fixed search function by binary parameters and position data.
- June 16, 2017
- added search option of the reference solar abundances and representative values for MW stars.
- changed the color set of plotted data points.
- June 11, 2017
- added search option of the reference solar abundances
- Users can select the solar abundances to be normalized in the plot of [X/Fe] and [X/H].
- The available options are Asplund et al. (2009), Grevesse et al. (1996), and Anders & Grevesse (1989).
- added search option of representative values.
- Users can choose the representative values if specified values (abundances, stellar parameters, etc) are reported by multiple papers.
- The available options are mean and median of all the available data, and the value subject to the priority parameter.
- Note that this option is to use the classification of stars by abundances and stellar parameters and is not applicable to the data retrieval system for dwarf galaxies.
- added search option of the reference solar abundances
- May 24, 2017
- Bug fix: “plot one” option did not work properly.
- May 23, 2017

-
Object names are unified according to the SIMBAD database. Multiple definitions of object names are removed since this version.
