The Leicester Database &
Archive Service (LEDAS) is an online database service for astronomers,
providing access to source catalogues and digital data products, with
an emphasis towards high-energy astrophysics (X-ray) satellite data.
LEDAS provides access to the 1XMM and 2XMMp archives, the European
mirror of the Chandra Science Archive, and data products for ROSAT,
ASCA, Ginga and EXOSAT. These archives can be searched and data
downloaded via a straightforward web interface. Work is ongoing to link
LEDAS to AstroGrid and the international Virtual Observatory, providing
a seamless method of combining astronomical data from centres around
LEDAS has been a public facility since 1992. The LEDAS cluster now stores nearly 2TB of catalogue and archive data (see LEDAS home page, http://www.ledas.ac.uk/ ) and the data volume continues to grow rapidly. The service is very popular, receiving c.25,000 web hits per month, and providing data downloads of ~2GB per month.
