cds-question@unistra.frsurveysradio-sourcesA deep 0.4-GHz survey of a 4deg-diameter region in Hercules is reported. 232 sources brighter than 9.5 mJy were detected. In a simultaneous 1.4-GHz survey of the concentric area 1deg in diameter, 45 sources brighter than 1.7 mJy were detected. The differential 0.4-GHz radio source count is presented; it is in good agreement with that from other 5C surveys. This survey brings to 3220 the number of 0.4-GHz sources catalogued by the published 5C surveys.1995MNRAS.272..699Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/272/699CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/272/699https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/272/699http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/272/699https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/272/699https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/272/699http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/272/699GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/272/699/table1 (The 5C13 catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/272/699/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/272/699/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/272/699/table1?GETtext/xml+votable180.050000true237.61389142.86245430.0055555555555555565/2456-2457 2459 6/9803 9805-9807 9816-9818 9832-9833 9835 9840 9842-9843 9848 9850 9924https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/272/699?format=asciiRadiodefaultJ/MNRAS/272/699/table1The 5C13 cataloguerecnoRecord number assigned by the VizieR team.
