It is found that there is significant anticorrelation between {nu}_peak_ and L_peak_ for blazars. However, after Doppler correction the anticorrelation disappears. The jet cavity power (P_jet_) is estimated from the extended radio luminosity so that it is free of beaming effects. We find that there are significant anticorrelations between P_jet_ and the beam-corrected {nu}_peak_' for both blazars and radio galaxies, which supports the blazar sequence and the unification of blazars and radio galaxies (an alternative relationship is the correlation between jet power and {gamma}-ray photon index).</description><source format="bibcode">2015MNRAS.451.2750X</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/451/2750</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/743/171">J/ApJ/743/171 : The 2LAC catalog (Ackermann+, 2011)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/other/Sci/338.1445">J/other/Sci/338.1445 : Relativistic jets from black hole systems (Nemmen+ 2012)</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/MNRAS/451/2750</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/451/2750</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/451/2750</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/451/2750</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/451/2750</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/451/2750</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/MNRAS/451/2750/table1 (The Fermi blazar sample)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/451/2750/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/451/2750/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/451/2750/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>12.6721556</ra><dec>-9.4847806</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/60 579 911 2143 2228 2414 2836 4255 4572 4695 4770 4820 4964 5154 5353 5423 5483 5516 5546 5693 5723 5771 5817 5918 6015 6021 6067 6088 6101 6582 6647 6777 6948 7038 7045 7181 7235 7354 7389 7426 7448 7518 7548 7570 7896 7969 8299 8487 8515 8915 8945 9442 9460 9566 9612 9632 9676 9711 9723 9998 10183 10198 10249 10422 10466 10548 10572 10800 10843 10921 11153 11212 11242 11321 11430 11522 11631 11639 11649 12466 12604 12619 13353 13582 13927 15023 15059 15269 15286 16027 16059 16281 16298 17184 17414 17516 17541 17579 18035 18624 18661 18755 19088 19157 19190 19370 19398 19593 19831 20099 20777 21358 21768 21935 21960 21968 21972 22363 22658 22917 22950 23014 23099 23121 23127 23691 24084 24608 24775 24845 25196 25302 25542 25630 25677 25818 26131 26292 26297 26303 26983 27060 27310 27423 27524 28083 28479 28492 28498 28517 29570 31190 31407 31430 31451 31664 31894 32311 32345 32621 34123 34209 34572 35786 35801 36090 36554 38189 38953 40344 40353 43366 44247 44908 45011 46055 46142 46964 47014 47016 47057 48595 49071</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/451/2750?format=ascii</footprint><waveband>Gamma-ray</waveband></coverage><tableset><schema><name>default</name><table><name>J/MNRAS/451/2750/table1</name><description>The Fermi blazar sample</description><column><name>Type</name><description>Blazar type</description><ucd>src.class</ucd><dataType xsi:type="vs:VOTableType" arraysize="4*">char</dataType></column><column><name>recno</name><description>Record number assigned by the VizieR team.
