cds-question@unistra.frradio-sourcesradio-continuum-emissionradio-galaxiesWe report multiple epoch VLA/JVLA observations of 89 northern hemisphere sources, most with 37GHz flux density >1Jy, observed at 4.8, 8.5, 33.5, and 43.3GHz. The high frequency selection leads to a predominantly flat spectrum sample, with 85% of our sources being in the Planck Early Release Compact Source Catalog (ERCSC, Cat. VIII/88). These observations allow us to: 1) validate Planck's 30 and 44GHz flux density scale; 2) extend the radio spectral energy distributions of Planck sources to lower frequencies allowing for the full 5-857GHz regime to be studied; and 3) characterize the variability of these sources. At 30GHz and 44GHz, the JVLA and Planck flux densities agree to within ~3%. On timescales of less than two months the median variability of our sources is 2%. On timescales of about a year the median variability increases to 14%. Using the WMAP 7-year data, the 30GHz median variability on a 1-6 years timescale is 16%.2013A&A...549A.133Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/549/A133CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/88 : Planck Early Release Compact Source Catalogue (Planck, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/549/A133https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/549/A133http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/549/A133https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/549/A133https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/549/A133http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/549/A133GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/549/A133/table3 (VLA/JVLA source coordinates and flux densities)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/549/A133/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/549/A133/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/549/A133/table3?GETtext/xml+votable180.050000true1.55788722-6.393148610.0055555555555555566/1263 1546 1701 1782 2245 3675 3820 3886 4572 4695 4770 4820 5139 5448 5597 5693 5767 5806 5817 6641 6853 7896 7969 8031 10249 10422 10432 11430 11715 12352 12580 12588 12619 13410 13496 13693 13927 14737 14842 15067 15286 15509 15659 15819 15936 16027 16059 16093 16281 16298 17351 17579 18005 18035 18624 18661 18669 19088 19101 19190 19398 19622 20019 20099 21358 21437 21758 21924 21935 21968 22363 22396 22917 23121 23323 23416 24084 24123 24571 26292 26303 27060 27063 27417 27765 28083 28479 28492 29675 31894 31930 327643.313034785154005e-24 2.2164203218209282e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/549/A133?format=asciiRadiodefaultJ/A+A/549/A133/table3VLA/JVLA source coordinates and flux densitiesSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
