The SVO archive of hot subdwarfs.

Documentation

Web access: The archive system implements a very simple search interface that permits queries by coordinates and radius. A selection of the astrometric, photometric and physical parameters to be displayed in the table of results can also be done. The default search radius is set to 5 arcsec. The user can also select the maximum number of sources to return (with values from 10 to unlimited).
The result of the query is a HTML table with all the sources found in the archive within the requested radius. Detailed information on the output fields can be obtained placing the mouse over the name of the column. The archive implements the SAMP (Simple Application Messaging Protocol). SAMP allows Virtual Observatory applications to communicate with each other in a seamless and transparent way for the user. This way, the results of a query can be easily transferred to other VO applications.
The archive contains both candidates and spectroscopically confirmed hot subdwarfs. Confirmed hot subdwarfs are those with an entry in the MK_like_class column.
Frequently Asked Questions
- How to make a query by objId/SDSS_name/Teff/Fit_flag/Excess?
  - Click "Reset".
  - Tick "Don't use coordinates as search criterion".
  - Fill in the appropriate boxes in the "additional search fields".
- How to download the tables included in the paper Pérez-Fernández et al. (2015)?
  - Just click on the corresponding link in the "Data retrieval" page.
- What does a effective temperature of 55 000K mean?
  - 55 000K represents the upper limit of the TLUSTY models. As sdOs can reach higher temperatures, this value should be taken, in most cases, as just a lower limit in effective temperatures.
