cds-question@unistra.frsurveysradio-sourcesWe present a 74MHz survey of a 165deg^2^ region located near the north Galactic pole. This survey has an unprecedented combination of both resolution (25" FWHM) and sensitivity ({sigma} as low as 24mJy/beam). We detect 949 sources at the 5{sigma} level in this region, enough to begin exploring the nature of the 74MHz source population. We present differential source counts, spectral index measurements, and the size distribution as determined from counterparts in the high-resolution FIRST 1.4GHz survey, Cat. <VIII/71>.2004ApJS..150..417Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/150/417CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/71 : The FIRST Survey Catalog, Version 03Apr11 (Becker+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/150/417https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/150/417http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/150/417https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/150/417https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/150/417http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/150/417GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/150/417/table2 (Complete Source List)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/150/417/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/150/417/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/150/417/table2?GETtext/xml+votable180.050000true183.466583328.21552780.0055555555555555564/672 674 1758 1759 1780 1781 5/2600 2602 2603 2606 2692 2694 2700 7021 7023 7025 7026 7027 7030 7031 7129 7132 7133 7135 6/10376 10378 10379 10404 10406 10407 10418 10428 10430 10431 10772 10773 10774 10780 10782 10804 10808 10809 10884 28061 28063 28083 28089 28112 28114 28115 28118 28436 28437 28439 28445 28513 28536 28537 28625 28628 28629https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/150/417?format=asciiRadiodefaultJ/ApJS/150/417/table2Complete Source ListrecnoRecord number assigned by the VizieR team.
