The XMM optical/UV data was provided to MAST starting in 2006.
Updates are obtained weekly? from the Guest Observer Facility
at HEASARC. The data are accessible using the
XMM Search Form. The search results page
also has links to the XMM preview pages which allow individual
images to be displayed as gif images or using Aladin..
