cds-question@unistra.frsurveysradio-sourcespolarimetryThe Australia Telescope 20-GHz (AT20G) Survey is a blind survey of the whole southern sky at 20GHz (with follow-up observations at 4.8 and 8.6GHz) carried out with the Australia Telescope Compact Array from 2004 to 2007. The Bright Source Sample (BSS) is a complete flux-limited subsample of the AT20G Survey catalogue comprising 320 extragalactic (|b|>1.5{deg}) radio sources south of DE=-15{deg} with S_20GHz_>0/50Jy. Of these, 218 have near simultaneous observations at 8 and 5GHz. In this paper we present an analysis of radio spectral properties in total intensity and polarization, size, optical identifications and redshift distribution of the BSS sources.2008MNRAS.384..775Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/384/775CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/371/898 : Extragalactic radio sources selected at 20GHz (Sadler+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/384/775https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/384/775http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/384/775https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/384/775https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/384/775http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/384/775GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/384/775/AT20G (Australia Telescope 20GHz (AT20G) Survey: Bright Source Sample (BDD))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/384/775/AT20G?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/384/775/AT20G?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/384/775/AT20G?GETtext/xml+votable180.050000true1.1485417-47.60530560.0055555555555555566/16444 16483 16509 16592 16676 16720 16962 17019 17048 17052 17184 17186 17188 17414 20483 20594 20607 20610 20657 20725 20781 20783 20888 20929 20935 21020 21049 21121 21163 21266 24608 24615 24775 24796 24809 24845 24906 24931 24936 24941 24994 25016 25036 25094 25126 25196 25255-25256 28673 28799 29016 29072 29074 29193 29218 29384 29714 32841 32892 32910 32916 32961 33043 33081 33285 33549 33560 33570 33684 33825 33827 33829 33862 33881 34013 34038 34095 34104 34117 34123 34210 34264 34428 34461 34517 34534 34571-34572 34665 34675 34691 34870-34871 34931 34938 35079 35093 35141 35294 35318 35370 35432 35440 35501 35562 35590 35608 35651 35680 35706 35786 35801 36005 36100 36120 36139 36151 36155 36188 36230 36295 36417 36554 36928 36941 37190-37191 37203 37217 37238 37246 37269 37368 37385 37474 37675 37686 37735 37779 37819 37919 37942 37994 38039 38046 38128 38189 38277 38279 38416 38470 38474 38579 38663 38763 38787 38802 38916 38993 39181 39298 39489 39577 39592 39658 39752 39775 39848 39920 39974 40037 40060 40066 40131 40344 40360 40474 40479 40527 40533 40635 40637 40990 41043 41059 41072 41275 41310 41325 41335 41356 41423 41460 41511 41543 41618 41665 41701 41818 41903 41938 41942 42046 42188 42249 42366 42411 42471 42481-42482 42492 42515 42526 42540 42571 42726 42825 42853 42901 42980 43085 43112 43116 43122 43233 43259 43262 43281 43366 43483 43549 43566 43578 43822 43828 43936 44000 44034 44043 44069 44147 44170 44247 44293 44310 44449 44555 44614 44670 44705 44776 44805 45162 45164 45196 45371 45393 45409 45446 45567 45614 45621 45713 45763 45795 46055 46101 46174 46204 46214 46226 46251 46310 46337 46373 46404 46459 46568 46588 46721 46764 46782 46851 46868 46921 46963-46964 47016 47057 47080 47106-47107 47151 47154 47187 47268 47325 47327 47375 47534 47540 47585 47605 47747 47941 47943 48023 48123 48142 48388 48407 48421 48496 48595 48610 48797-48798 48846https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/384/775?format=asciiRadiodefaultJ/MNRAS/384/775/table1Follow-up observationsrecnoRecord number assigned by the VizieR team.
