Beginning of ReadMe : V/134 Atlas of Radio/X-ray associations (ARXA) (Flesch, 2010) ================================================================================ The atlas of radio/X-ray associations (ARXA) Flesch E. <Publ. Astron. Soc. Australia 27, 283 (2010)> =2010PASA...27..283F ================================================================================ ADC_Keywords: Radio sources ; X-ray sources ; Cross identifications Keywords: atlases ; catalogs ; X-rays: general ; X-rays: stars ; radio continuum: stars Abstract: An all-sky comprehensive catalogue of calculated radio and X-ray associations to optical objects is presented. Included are X-ray sources from XMM-Newton, Chandra and ROSAT catalogues, radio sources from NVSS, FIRST and SUMSS catalogues, and optical data, identifications and redshifts from the APM, USNO-A, SDSS-DR7 and the extant literature. This "Atlas of Radio/X-ray Associations" inherits many techniques from the predecessor Quasars.org catalog (Flesch 2004, Cat. J/A+A/427/387), but object selection is changed and processing tweaked. Optical objects presented are those which are calculated with 40% confidence to be associated with radio/X-ray detections, totalling 602570 objects in all, including 23681 double radio lobe detections. For each of these optical objects I display the calculated percentage probabilities of its being a QSO, galaxy, star, or erroneous radio / X-ray association, plus any identification from the literature. The catalogue includes 105568 uninvestigated objects listed as 40% to >99% likely to be a QSO. The catalogue is available at http://quasars.org/arxa.htm . Description: 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.
