cds-question@unistra.frgalaxy-clustersradio-galaxiesWe report on 1.4GHZ continuum observations for 11 VLA fields, using the D-configuration, which contain the A group of the Cancer Cluster. Sixteen Zwicky spiral galaxies in the Cancer Cluster were detected, but no ellipticals. We corroborate the finding that spiral galaxies with close companions tend to have enhanced radio emission. Over 200 continuum sources beyond the Cancer Cluster are tabulated. The spectral index (relative to 610MHz) is given for many of the sources, including some of the Zwicky galaxies. There is a suggestion for a nonuniform number surface-density distribution of the sources, not correlated with the Cancer Cluster. Possible predictions of such nonuniformities, from assumptions on " super-superclusters," are discussed.1987ApJ...317..102Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/317/102CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/317/102https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/317/102http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/317/102https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/317/102https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/317/102http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/317/102GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/317/102/table2 (List of continuum sources observed in VLA fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/317/102/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/317/102/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/317/102/table2?GETtext/xml+votable180.050000true124.01859920.8118450.0055555555555555566/4715 4718 4719 4730 4801 4803 4804 4805 48062.4696718532768785e-21 3.953759050367298e-21https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/317/102?format=asciiRadiodefaultJ/ApJ/317/102/table2List of continuum sources observed in VLA fieldsrecnoRecord number assigned by the VizieR team.
