xmm-newton serendipitous uv source catalogue
summary available through the esa xsa system and vo from july queries before then: martin still 700,000 uv sources from 2,388 xmm-newton pointings. 3-colour data across the galex nuv band. simultaneous x-ray and optical data. source variability from multiple exposures and pointings. catalogue will go deeper still when individual exposures are mosaiced in the xmm sas pipeline. swift-uvot uv source archive to follow.
