cds-question@unistra.fractive-galactic-nucleiradio-galaxiesradio-continuum-emissionWe study the correlation between the emission from the broad-line region (BLR) and the emission in other wavelength ranges (from radio to x-ray) for the sample of 37 blazars (25 flat-spectrum radio quasars (FSRQs) and 10 BL Lac blazars). Studying the relation between luminosities in various wavebands and the BLR luminosity is an effective method to examine the connection between the accretion rate and the luminosity of the jet.We used simultaneous RATAN-600measurements of blazar flux densities at six frequencies: 1.1, 2.3, 4.8, 7.7, 11.2, and 21.7GHz. The observational data from other bands was taken from the literature. To determine the effect produced by the state of the object on the correlation, for the radio data we used the measurements obtained with the RATAN-600 in two states-namely, the maximum and minimum flux density values.We show that at some frequencies of the radio band, there exists a correlation of emission with the emission in the BLR for two types of blazars. In the FSRQ and BL Lac blazars, the correlation between the flux from the BLR and the flux in the radio band is indistinguishable in all cases, except for the case when a strong flux density variation was considered for the BL Lac-type of blazars (tens of percent). At the same time, the levels of significance for BL Lac (at certain frequencies p is worse than 0.05) in the active state indicate only the probable presence of connection. On the example of the sample, we show that the variability of emission significantly affects the level of correlation. Our results are consistent with the theoretical predictions about the close relationship of the accretion disk and the jet in blazars.2014AstBu..69..266Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/69.266CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/495/691 : Blazars multifrequency catalogue, Roma-BZCAT (Massaro+ 2009)J/MNRAS/450/2658 : RATAN-600 flux densities of 123 blazars (Mufakharov+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/69.266https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/69.266http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/69.266https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/69.266https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/69.266http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/69.266GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/69.266/table2 (Data for 37 objects)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/69.266/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/69.266/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/69.266/table2?GETtext/xml+votable180.050000true34.378389473.82572810.0055555555555555566/579 3886 4695 4805 5597 5693 5767 5806 6507 6641 6853 7570 7969 8345 8487 9442 9460 9633 15286 16093 16298 18661 19101 19398 20099 21935 23121 24608 25630 26131 26292 27060 31430 44908 47057 48595 486107.28867668531662e-25 1.437857147309737e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/AstBu/69.266?format=asciiRadiodefaultJ/other/AstBu/69.266/table2Data for 37 objectsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
