  2. content: sources comparison with GALEX source sample • galex has  sky coverage • galex has bluer energy sensitivity • simultaneous 2xmm source data • less source confusion from om psf • om is deeper than galex ais (mAB < 20.5) • three om colours in nuv passband • om sensitivity within the galex-sdss energy gap • variability on hour and year timescales The X-ray Universe 2008

  3. content: source depth all sources without quality flags The X-ray Universe 2008

  4. content: astrometry astrometric correction using usno-b1.0 The X-ray Universe 2008

  5. content: sky coverage filtered xmm pointings included within catalogue The X-ray Universe 2008

  6. quality flagging number of quality issues decreases into the uv The X-ray Universe 2008

  7. colour-colour planes observed and computed tracks of galaxies and stars The X-ray Universe 2008

  8. colour-colour planes main sequence and galactic dust columns The X-ray Universe 2008

  9. colour-colour planes extra-galactic sources and redshift The X-ray Universe 2008

  10. 2xmm variable sources uv counterparts The X-ray Universe 2008

  11. xmm-newton serendipitous uv source catalogue summary • available through the esa xsa system and vo from july 2008. queries before then: martin still mds@mssl.ucl.ac.uk • 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. The X-ray Universe 2008
