cds-question@unistra.frradio-sourcesThe results of observations of a complete sample of flat-spectrum radio sources with spectral indices {alpha}>-0.5 are presented. The sample was selected from the Zelenchuk Survey at 3.9GHz (See Cat. <VIII/49>) and contains all sources with declinations 4-6 degrees, galactic latitudes |b|>10 degrees, and 3.9-GHz fluxes >200mJy. Spectra at 0.97-21.7 GHz were obtained for all 69 sample sources. The spectra were classified and a correlation between variability amplitude and spectrum shape was found.2000AZh....77..407Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/77/407CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/49 : The Zelenchuk Surveys (Amirkhanyan+, 1989)J/AZh/72/291 : Variability at Frequencies 3.9 and 7.5 GHz (Gorshkov+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/77/407https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/77/407http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/77/407https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/77/407https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/77/407http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/77/407GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/77/407/table3 (Spectral parameters of sources with separated components)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/77/407/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/77/407/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/77/407/table3?GETtext/xml+votable180.050000true1.33455415.40280510.005555555555555556Cone search capability for table J/AZh/77/407/table5 (Parameters of the sources whose spectra could not be separated into components)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/77/407/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/77/407/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/77/407/table5?GETtext/xml+votable180.050000true39.96401434.27268990.0055555555555555566/27 49 4122 8207 8220 12311 12352 17791 17877 17898 18155 18158 18214 18242 18907 18926 19157 19162 19166 19223 19483 19493 19500 19523 21886 21972 21987 21990 21997 22298 22305 23014 23015 23257 23259 23261 23274 23323 23333 23335 23336 26073 26083 26089 26303 26340 26345 27096 27417 27433 27436 27675 27689 27712 30171 30489 30512 31190 31211 31439 31444 31451 31461 31508 31511 31523 31529 317706.427287672772141e-25 1.437857147309737e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/77/407?format=asciiRadiodefaultJ/AZh/77/407/table1Flux densities of the radio sourcesrecnoRecord number assigned by the VizieR team.
