Known problems – SAGA database

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.
