cds-question@unistra.frastronomical-object-identificationsurveysradio-sourcesWe report the results of an extragalactic point-source search using the 61 and 94GHz (V- and W-band) temperature maps from the Wilkinson Microwave Anisotropy Probe (WMAP). Applying a method that cancels the "noise" due to the CMB anisotropy signal, we find in the |b|>10{deg} region 31 sources in the first-year maps and 64 sources in the three-year co-added maps at a 5{sigma} level. The 1{sigma} position uncertainties are 1.6' and 1.4', respectively. The increased detections and improved positional accuracy are expected from the higher signal-to-noise ratio of the WMAP three-year data. All sources detected in the first-year maps are repeatedly detected in the three-year maps, which is a strong indication of the consistency of this method. Of all the sources, 97% are identified with either the WMAP three-year source catalog or plausible extrapolations of lower frequency data, which indicates that our method is also reliable. The two unidentified sources have been recently confirmed to be false detections, using the WMAP five-year data. We derive the source count distribution at the WMAP V band by combining our verified detections with sources from the WMAP three-year catalog. If we assume that the effect of source clustering is negligible, the contribution to the power spectrum from faint sources below 0.75Jy is estimated to be (2.4+/-0.8)x10^-3^uK^2^sr for the V band, which implies a source correction amplitude of A=0.012+/-0.004uK^2^sr.2008ApJ...681..747Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/681/747CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/508/107 : WMAP3 catalogue (Giommi+, 2009)J/ApJS/180/283 : WMAP source catalog (Wright+, 2009)J/AZh/85/483 : Sources from the WMAP catalog (Vol'vach+, 2008)J/MNRAS/384/775 : Bright Source Sample of AT20G Survey (Massardi+, 2008)J/ApJS/170/288 : WMAP 3 Year Temperature Analysis (Hinshaw+, 2007)J/ApJS/171/61 : All-Sky Survey of Flat-Spectrum Radio Sources (Healey+,J/ApJS/170/108 : NEWPS_5{sigma}_ source catalogue from WMAP (Lopez-Caniego+,J/ApJS/148/97 : The WMAP First Year Source Catalog (WMAP1) (Bennett+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/681/747https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/681/747http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/681/747https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/681/747https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/681/747http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/681/747GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/681/747/table1 (Point-source catalog: three years)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/681/747/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/681/747/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/681/747/table1?GETtext/xml+votable180.050000true1.55833-6.395560.0055555555555555566/911 1559 1565 1701 2836 4695 5767 7969 9442 9460 9633 10422 13927 16059 16093 17351 18035 18624 18661 18669 19190 20099 21121 21266 21439 21458 22854 22855 23121 23286 25630 26131 26292 27060 27310 27765 29570 29675 31080 31894 32657 33094 33098 33102 33126 34013 34104 34123 34210 34264 34494 34517 35079 36941 37385 38260 39339 40527 41335 42977 43262 45446 46964 480234.041902437887886e-23 4.041902437887886e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/681/747?format=asciiRadiodefaultJ/ApJ/681/747/table1Point-source catalog: three yearsrecnoRecord number assigned by the VizieR team.
