The XMM-Newton Science Archive
  The XMM-NEWTON Science Archive (XSA) is being developed within the XMM-NEWTON Science Operations Centre at the ESA VILSPA Satellite Tracking Station of Villafranca del Castillo, near Madrid in Spain. The first public version was released on April 15, 2002.   Based on the ISO Data Archive architecture and design, the XSA is accessible from the World Wide Web through a Java interface at http://xmm.vilspa.esa.es/xsa that allows: - powerful and complex queries against the observations and exposure catalogue for the first release and against the source catalogue in future releases - configurable results display, including product visualization tools - customisable product retrieval via a shopping basket - selection of product level - product retrieval via FTP or CDROM - proprietary rights protection for both display and data request   The XSA will also be ready to provide inter-operability with other archives and applications.
