These redshifts are measured from the narrow emission lines of these objects and are accurate to at least one part in 10^4^. For each object we determine a redshift from high- and low-ionization lines separately, as well as an average redshift from all the available lines. We find that in about 15% of cases, the low-ionization lines yield a slightly higher redshift than the high-ionization lines; the average redshift difference amounts to a velocity difference of approximately 80km/s. In addition to the redshift measurements we also report revised redshifts for two objects as well as new classifications for three narrow-line objects.</description><source format="bibcode">2004ApJS..150..181E</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/150/181</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/599/886">J/ApJ/599/886 : Emission lines of radio-loud AGN (Eracleous+, 2003)</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/ApJS/150/181</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/150/181</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/150/181</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/150/181</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/150/181</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/150/181</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/ApJS/150/181/table2 (Measured Redshifts)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/150/181/table2?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/150/181/table2?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/150/181/table2?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>4.91575</ra><dec>26.04786</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/513 928 1263 1450 1549 1696 2134 2164 2201 4118 4252 4696 5312 5415 5597 6264 6466 7061 7570 7642 8525 8631 9181 9375 9490 9497 9707 9772 10217 10307 10321 10780 11203 11402 11408 12604 14858 15064 16301 17052 17782 17979 17999 18561 18683 18769 18895 18981 19285 19413 19724 20042 20116 20290 21169 21758 21955 22976 23269 24615 24867 24908 25580 25630 25673 25742 26290 26374 26736 26769 27023 27382 27561 27580 28138 28419 28527 28589 30773 31190 31399 31983 32344 32948 32961 34065 34090 34104 34510 35082 35983 38383 38836 40265 40332 40344 40704 40838 43417 43461 43743 44043 44650 45339 46588 46762 46851 46951 46984 47352</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/150/181?format=ascii</footprint><waveband>Optical</waveband><waveband>Radio</waveband></coverage><tableset><schema><name>default</name><table><name>J/ApJS/150/181/table2</name><description>Measured Redshifts</description><column><name>recno</name><description>Record number assigned by the VizieR team.
