The Atlas of Radio/X-ray Associations (ARXA, 2010 PASA 27 283)

These are 602,570 optical objects which are associated to radio/X-ray detections from the NVSS, FIRST, SUMSS, XMM-Newton, 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.

15-May-2016 -- Supplemental file for ARXA now available (unpublished).

In the 6 years since ARXA was published, I've added USNO-B data into the optical background, additional X-ray data from XMM, Chandra and Swift, and additional radio data from FIRST updates. ARXA processing yields 424,348 additional radio/X-ray associations (calculated at 40%-100% likelihood of the association being true). This extra data is written as a file with the same data layout as ARXA. Swift detections are added into the WGA column to keep the data layout the same.
