The survey was conducted at a frequency of 4.7GHz using a three-beam radiometer complex installed in the focus of the Western Sector of the RATAN-600 radio telescope in 2018-2019. Based on the measurements taken and the data collected in the CATS astrophysical catalog database, the radio spectra of the objects were constructed. For a quarter of all detected sources, data at frequencies above 4 GHz were obtained for the first time, and for the rest they were supplemented. The variability of radiation sources on the scales of the year, from days to months, has been studied. The greatest change in the radio flux was found in the blazar B2 1324+22. The search for daily variability was carried out for the 26 brightest sources with an average value of S_4.7_~250mJy. All sources are identified with objects from optical and infrared catalogs. The radio luminosity was calculated for 112 objects with a known redshift.2024AstBu..79...36Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/79.36CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/79.36https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/79.36http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/79.36https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/79.36https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/79.36http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/79.36GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/79.36/sources (List of the 26 bright sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/79.36/sources?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/79.36/sources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/79.36/sources?GETtext/xml+votable180.050000true2.937521.986670.0055555555555555566/693 698 774 1029 2053 4538 5125 8565 8902 8976 9225 10249 12918 13001 13061 19893-19894 19898 23990 24326 28279 28341 32181 32442 32517 325213.114252571662517e-24 3.114252571662517e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/AstBu/79.36?format=asciiOpticalRadiodefaultJ/other/AstBu/79.36/sourcesList of the 26 bright sourcesrecnoRecord number assigned by the VizieR team.
