There are 171 sources listed in the catalog due to multiple components for some of the radio sources. Flux densities were measured at 327 MHz by lunar occultation with the Ooty Telescope. Flux densities have also been measured at 18 cm (1669 MHz) and 21 cm (1413 MHz) using the Nancay telescope. Optical identifications on the basis of the radio positions and angular structures are given. This catalog is a merge of table 1 and table 2 from the publication.</description><source format="bibcode">1989A&amp;AS...80..215A</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/80/215</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></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/A+AS/80/215</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/80/215</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/80/215</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/80/215</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/80/215</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/80/215</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/A+AS/80/215/radlunar (Radio Source Parameters From Lunar Occultation, Observations (-19{deg} to 19{deg}))</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/80/215/radlunar?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/80/215/radlunar?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/80/215/radlunar?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>0.7383731</ra><dec>-0.4128992</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>5/4537 6/188 232 322 324 385 4183 4279 4294 4647 4655 4738 4744 18090 18103 18132-18133 18140-18142 18144 18146-18147 18235 18238-18239 18320 18324 18635 18644 18646 18729 18739 18742 18745 18758 23546 23805 23863 23882-23883 23906 23970 23976 24146 24152 25684 25781 26248 26968 26970 26983 26994 27071 27105 27421 27423 27554 29045-29046 29083 29271 29291 29335 29342 29703 29705 44383 44405 44486 44492-44493 44513 48825 48849 48868 48927 48948 48965 48967-48968 48972-48973</spatial><spectral>2.166724697358042e-25 1.1058910308736551e-24</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/80/215?format=ascii</footprint><waveband>Radio</waveband></coverage><tableset><schema><name>default</name><table><name>J/A+AS/80/215/radlunar</name><description>Radio Source Parameters From Lunar Occultation, Observations (-19{deg} to 19{deg})</description><column><name>recno</name><description>Record number assigned by the VizieR team.
