We checked the relationships between their proper motions, redshifts, {beta}_app_ and 5GHz flux densities. Our analysis shows that the radio emission is strongly boosted by the Doppler effect. The superluminal motion and the relativistic beaming boosting effect are, to some extent, the same in active galactic nuclei.</description><source format="bibcode">2008ChJAA...8..385Z</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ChJAA/8.385</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJ/430/467">J/ApJ/430/467 : Extragalactic sources superluminal motions (Vermeulen+, 1994)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ChJAA/8.385</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ChJAA/8.385</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ChJAA/8.385</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ChJAA/8.385</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ChJAA/8.385</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ChJAA/8.385</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/other/ChJAA/8.385/table1 (The 224 individual feature data of 123 superluminal sources)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ChJAA/8.385/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/other/ChJAA/8.385/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ChJAA/8.385/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>4.9407767</ra><dec>73.4583381</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/556 579 700 911 1263 1546 1701 2052 2214 2414 2631 2710 3024 3820 3886 3971 4054 4572 4695 4770 4820 5154 5353 5423 5767 5806 5817 6033 6164 6252 6507 6751 7296 7349 7371 7404 7508 7763 7873 7896 7969 8031 8057 8123 8299 8528 9347 9442 9460 9490 9612 9633 10422 11430 11639 11715 12047 12241 13156 13496 13789 13927 14520 14737 14744 14831 15023 15067 15286 15936 16093 16281 16298 16301 17184 18035 18506 18661 19190 19398 20099 21935 21968 21972 22363 22396 22917 22950 23099 23121 23323 24084 24571 25302 25630 25864 26131 26292 26491 27060 27514 27765 28083 28479 28492 28643 29016 29570 31391 31451 31559 31664 31894 32594 35079 37385 42901 42980 43262 44805 44908 45763</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ChJAA/8.385?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/other/ChJAA/8.385/refs</name><description>References</description><column><name>recno</name><description>Record number assigned by the VizieR team.
