Abstract
An interactive database interface to the subdwarf catalogue has been designed and prototyped. The implementation is still under development, but is already fully functional. More than 2300 stars from an updated edition of the subdwarf catalogue have been loaded into the database, and additional photometric data from many other sources have been included. The database tools include advanced search capabilities in coordinate, magnitude and colour space. Output tables can be generated in HTML with hyperlinks to automatically generated finding charts, the SIMBAD database, the Aladin viewer, as well as an internal data sheet generated for each database entry. Search results can be visualised automatically as interactive position, magnitude or colour diagrams. Access to the database is currently restricted to those who wish to contribute to the development of the project.
