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 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 . 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.

Note (1): A blank value indicates this object has been not identified up to now. If the catalogue is "QO" (QORG), name is e.g., QORG J012345.6+012345. If the catalogue is blank, name is of the form ARXA J012345.6+012345, using the J2000 location column as the name. I am tempted to use names from a sequential name list, e.g., "Bertfriede", "Bertha", "Berthar", etc, but suspect it would not take. Note (2): Classification from the Veron catalog takes precedence over other values. Legend: Q = QSO from the literature, with redshift (21735 of these) A = AGN (from Veron, or Seyfert galaxy). (6941) B = Bl Lac object (803) q = NBCKDE photometric quasar (>60%). Redshift rounded to 0.1z. G = galaxy (89,731) L = lenticular liner galaxy(3 stated) N = narrow emission line galaxy (93 stated) M = multiple-galaxy cluster (179) g = MegaZLRG photometric galaxy (>80%). Redshift rounded to 0.01z. S = star (13,841) W = white dwarf star. H = HI/starburst region. R = radio association displayed. X = X-ray association displayed. 2 = double radio lobe identified. Note (3): Magnitudes have been recalibrated from the original APM/USNO-A values. However, USNO-A UKST objects fainter than 18.5 can have large errors. Extended objects brighter than mag 13 can be represented as far too bright. If "opt" is r/b/g/i/w, magnitudes are from the object's source catalog. Note (4): Legend: p = optical magnitudes are POSS-I E and O. r/b/g/i/w = optical magnitudes from the source catalog (e.g. SDSS, 2QZ, etc). This is presented if object was not found in APM/USNO-A. (none of the above) = optical magnitudes are UKST R and Bj. v = variability nominally detected for both red & blue m = proper motion nominally detected. ? = "inferred" object -- position and magnitude is approximate for one or both colours where PSF is listed as "n". Note (5): The APM provides PSF class, the USNO-A does not. Some QSO catalogs like the SDSS give morphology which we use here for objects not found in the APM. Legend: - = stellar PSF (usually from APM) 1 = fuzzy PSF (usually from APM) 2 = extended PSF. Can be galaxies, merged stars, etc. n = no PSF available, usually USNO-A sourced. x = not seen in this color (fainter than plate depth, or confused, etc.) Note (6): Legend and references: 2d/2G = 2dFGRS, Colless M. et al. 2001MNRAS.328.1039C, Cat.
