VizieR Online Data Catalog: Atlas of Radio/X-ray associations (ARXA) (Flesch, 2010)

This is a compendium of all catalogued or APM/USNO-A optical objects which are found to be associated to XMM, Chandra, RASS, HRI, PSPC or WGA X-ray detections, or to NVSS, FIRST or SUMSS radio detections. All detections are displayed, plus double radio lobes where found. The counts are:

Optical objects - 602,570 NVSS - 266,148 core associations, plus 8309 double lobes. FIRST - 173,383 core associations, plus 12,844 double lobes. SUMSS - 59,138 core associations, plus 2529 double lobes. XMM associations - 57,778 Chandra associations - 32,951 ROSAT RASS - 47,486 ROSAT HRI - 15,523 ROSAT PSPC - 35,607 WGA - 24,226

Each optical object is shown as one line bearing the J2000 coordinates, the object name (from the literature where available), APM & USNO-A sourced red & blue photometry, redshift, the source catalogs for the name and redshift, calculated odds that the object is a quasar, galaxy, star, or erroneous association, and the radio & X-ray identifiers, up to 10 of them possible although usually just 1 or 2.
