The Atlas of Radio/X-ray
Associations (ARXA, 2010 PASA 27 283)
are 602 570 optical objects which are associated to radio/X-ray detections from
the NVSS, FIRST, SUMSS, XMM, Chandra, or ROSAT RASS, PSPC, HRI and WGA survey
catalogs. All association detections are shown, across all these catalogs. Also
displayed: the calculated probability that the optical object is in turn a quasar,
galaxy, star, or erroneous association. The optical object is identified from
the literature, if known.
