cds-question@unistra.frsurveysradio-sourcesWe present some first results on the variability, polarization and general properties of radio sources selected at 20GHz, the highest frequency at which a sensitive radio survey has been carried out over a large area of sky. Sources with flux densities above 100mJy in the Australia Telescope Compact Array 20GHz pilot survey at declination 60{deg} to 70{deg} were observed at up to three epochs during 2002-04, including near-simultaneous measurements at 5, 8 and 18GHz in 2003. Of the 173 sources detected, 65 per cent are candidate QSOs or BL Lac objects, 20 per cent galaxies and 15 per cent faint (bJ>22mag) optical objects or blank fields.2006MNRAS.371..898Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/371/898CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/6 : Polarization of Extragalactic Radio Sources (Eichendorf+ 1980)VIII/32 : Extragalactic sources at 5GHz (Jenkins+ 1977)VIII/78 : Sydney University Molonglo Sky Survey (SUMSS) (Mauch+ 2006)J/A+AS/135/571 : Extragalactic radio sources polarization (Zukowski+, 1999)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/371/898https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/371/898http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/371/898https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/371/898https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/371/898http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/371/898GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/371/898/table3 (Radio spectra and optical IDs for extragalactic 18GHz sources (|b|>10{deg}), and excluding objects within of the LMC centre)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/898/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/898/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/898/table3?GETtext/xml+votable180.050000true1.836875-61.21855560.0055555555555555566/33011 33143 33151 33158 33166 33172-33173 33176 33180 33189 33195 33217-33218 33229 33238-33239 33259 33342 33345 33356-33357 33382 33388 33391 33398-33399 33406 33419 33430 33460 33463 33471 33476 33489 33504 33537 33544 33546 33549 33551 33558 33560 33570 33575 33795 33816 33825 33827 33829 33833 34854 34856 37119 37254 37283 37285 37438 37450 37453 37466 37469 37474 37480-37481 37519 37529 37552 37559 37587 37602 37642-37643 37667 37675 38916 38918 38937 38948 38950 38952-38953 38956 41275 41290 41302 41310-41311 41325 41330 41335 41355-41356 41358 41988 41991 41996 42012 42017 42048 45295 45303 45307 45311 45371 45393 45400-45401 45409 45415 45424 45434 45446 45453 45463 45483 45487 45490-45491 45493 45497 45511 45513-45514 45522 45540 45599 45619 45621 45645 45647-45648 45655 45660 45681 45690 45695 45704 45709 45712-45713 45724 45727 45732-45733 45761 45763 45770 45774 45792 45795 45835 45843 45846 46101-46102 46119 46123-46124 47106-47107 47110 47112 47122https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/371/898?format=asciiRadiodefaultJ/MNRAS/371/898/table3Radio spectra and optical IDs for extragalactic 18GHz sources (|b|>10{deg}), and excluding objects within of the LMC centrerecnoRecord number assigned by the VizieR team.
