cds-question@unistra.frradio-sourcesThe detection of point sources in cosmic microwave background maps is usually based on a single-frequency approach, whereby maps at each frequency are filtered separately and the spectral information on the sources is derived combining the results at the different frequencies. In contrast, in the case of multifrequency detection methods, source detection and spectral information are tightly interconnected in order to increase the source detection efficiency. In this work we apply the matched multifiltermethod to the detection of point sources in the Wilkinson Microwave Anisotropy Probe (WMAP) 7-year data at 61 and 94GHz. This linear filtering technique takes into account the spatial and the cross-power spectrum information at the same time using the spectral behaviour of the sources without making any a priori assumption about it.2013MNRAS.428.3048Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/428/3048CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/88 : Planck Early Release Compact Source Catalogue (Planck, 2011)J/MNRAS/392/733 : The NEWPS catalog from WMAP 5-yr survey (Massardi+, 2009)J/ApJS/192/15 : Seven-year WMAP catalog (Gold+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/428/3048https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/428/3048http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/428/3048https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/428/3048https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/428/3048http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/428/3048GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/428/3048/sources (Positions and identifications of the sources detected, matching galactic (table1) or extragalactic radio (table2) sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/3048/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/3048/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/3048/sources?GETtext/xml+votable180.050000true13.23756.5760.0055555555555555566/582 862 911 1263 1546 1559 1701 2836 3011 3820 3886 4695 5596 5767 5817 6853 7896 7969 8858 9442 9460 9545 9633 10166 10422 11066 11430 11715 12619 13496 13927 14029 14744 15023 15067 15667 16027 16049 16059 16093 16298 16676 17351 17414 18506 18624 18661 19088 19101 19190 19398 20099 20888 20935 21121 21266 21436 21439 21458 21758 21935 21968 22396 22855 23099 23121 23323 24185 24845 25196 25630 26131 26292 27060 27417 27765 28479 29016 29570 29675 31080 31430 31451 31894 32657 32841 33549 33684 34013 34095 34104 34123 34258 34461 34494 34517 34572 35079 35440 35562 35801 36100 36608 36941 37388 38261 38761 40060 40527 41072 41310 42901 42981 43262 43366 44247 45446 46055 46308 46337 46384 46964 47016 47542 47828 48023 48123 48798 488466.228505396089529e-23 6.228505396089529e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/428/3048?format=asciiRadiodefaultJ/MNRAS/428/3048/sourcesPositions and identifications of the sources detected, matching galactic (table1) or extragalactic radio (table2) sourcesrecnoRecord number assigned by the VizieR team.
