cds-question@unistra.frsurveysradio-sourcesAs a pilot study for the first all-sky radio survey at short wavelengths, we have observed 1216deg^2^ of the southern sky at 18GHz (16mm) using a novel wide-band (3.4-GHz bandwidth) analogue correlator on one baseline of the Australia Telescope Compact Array. We scanned a region of sky between declination -71{deg} and -59{deg} with an rms noise level of 15mJy. Follow-up radio imaging of candidate sources above a 4{sigma} detection limit of 60mJy resulted in 221 confirmed detections, for which we have measured accurate positions and flux densities. For extragalactic sources, the survey is roughly 70 per cent complete at a flux density of 126mJy and 95 per cent complete above 300mJy. Almost half the detected sources lie within a few degrees of the Galactic plane, but there are 123 sources with |b|>5{deg}, which can be assumed to be extragalactic.2004MNRAS.354..305Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/354/305CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/38 : The Parkes-MIT-NRAO 4.85GHz (PMN) Surveys (Griffith+ 1993-1996)VIII/70 : Sydney University Molonglo Sky Survey (SUMSS) (Mauch+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/354/305https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/354/305http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/354/305https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/354/305https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/354/305http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/354/305GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/354/305/table2 (Measured positions and flux densities for confirmed 18GHz detections)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/354/305/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/354/305/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/354/305/table2?GETtext/xml+votable180.050000true6.0269583-68.34841670.005555555555555556Cone search capability for table J/MNRAS/354/305/table5 (Radio spectra and optical IDs for extragalactic 18-GHz sources (|b|>5{deg}, and excluding objects within 5.5{deg} of the LMC centre).)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/354/305/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/354/305/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/354/305/table5?GETtext/xml+votable180.050000true6.0269583-68.34841670.0055555555555555565/10419 6/33022 33094 33101-33102 33116 33120 33128 33134 33143 33158 33173 33180 33189 33195 33217-33218 33220 33238 33259 33342 33345 33353 33391 33406 33419 33430 33460 33463 33471-33472 33476 33489 33498 33537 33549 33558 33570 33796 33816 33825 33829 33833 34854 37191 37203 37215 37217 37290 37307 37450 37469 37471 37535 37557 37642 37674 37897 37899 37923-37924 41275 41302 41310-41311 41325 41330 41356 41361 41374 41390 41543 41552 41574 41578 41607 41619 41638 41655 41665 41669 41673 41675 41681-41683 41685 41687 41696 41701 41730 41743 41763 41767 41770 41772 41778 41856 41988 41991 41996 42012 42017 42048 43012-43013 43015 43017-43019 43021 43024 43027 43040 43046 45295 45303 45311 45383 45393 45400-45401 45403 45409 45412 45424 45446 45453 45463 45483 45493 45511 45513-45514 45522 45540 45599 45619 45621 45647 45655 45690 45695 45701 45704 45707 45712-45713 45732-45733 45752 45763 45774 45779 45792 45795 45843 45857 46101 46119 46121 47106-47107 47110 47112 47122https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/354/305?format=asciiRadiodefaultJ/MNRAS/354/305/table2Measured positions and flux densities for confirmed 18GHz detectionsrecnoRecord number assigned by the VizieR team.
