The sample includes those sources noted in the Molonglo Reference Catalog (MRC) (Cat.&lt;VIII/16&gt;) as extended (larger than 1'), as well as those noted as multiple (within 8' of another ssource and possibly related). The sample is representative of the strong extended extragalactic radio sources of the southern sky, but is not statistically complete. Positions, flux densities, and sizes are given for all sources, and those sources which have been confirmed as extended MRC sources are flagged. In addition, optical positions, magnitudes, redshifts, and identifications are given for 201 of the sources. These data were originally published in two tables which have been merged in this version.</description><source format="bibcode">1992ApJS...80..137J</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/80/137</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/ApJS/80/137</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/80/137</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/80/137</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/80/137</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/80/137</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/80/137</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/80/137/southext (Structure of Southern Extended Extragalactic Radio Sources)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/80/137/southext?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/80/137/southext?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/80/137/southext?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>1.560979</ra><dec>-83.099903</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/16484 20483 20527 20577 24608 24614 24710 24722 28720 32815 32898 32908 33022 33065 33083 33130 33131 33143 33234 33235 33282 33291 33313 33316 33337 33369 33440 33460 33505 33575 33731 33765 33798 33816 33922 33968 34007 34073 34086 34090 34104 34233 34293 34303 34311 34327 34375 34441 34463 34473 34493 34513 34535 34545 34648 34863 34867 35001 35003 35026 35040 35056 35097 35098 35110 35113 35125 35134 35135 35195 35221 35264 35344 35353 35398 35434 35447 35453 35608 35713 36944 37189 37191 37226 37277 37308 37330 37411 37412 37441 37453 37475 37546 37651 37687 37690 37734 37776 37987 38174 38260 38364 38376 38517 38558 38585 38605 38624 38720 38791 38793 38819 38935 38937 38963 38974 39012 39043 39073 39077 39087 39144 39175 39181 39368 39460 39492 39614 39694 39714 39715 39722 39725 39961 39982 39995 40081 40105 41051 41096 41239 41414 41418 41423 41434 41477 41510 41584 41615 41626 41831 41870 41903 41928 41943 41991 41995 42003 42060 42080 42235 42245 42278 42322 42530 42563 42569 42570 42571 42581 42700 42743 43010 43072 43233 43259 43262 43285 43389 43417 43451 43461 43471 43537 43590 43600 43646 43806 43912 43913 43914 43925 44068 44129 45059 45121 45197 45225 45227 45243 45263 45269 45283 45339 45418 45446 45478 45484 45522 45525 45751 45755 45793 45823 45827 45834 45859 45862 45883 45906 45907 45908 45912 45915 45961 45984 45985 45989 45991 46095 46101 46146 46237 46265 46268 46273 46308 46310 46348 46350 46351 46442 46644 46715 46801 46848 46911 47008 47151 47174 47178 47204 47270 47393 47405 47462 47483 47486 47508 47533 47595 47613 47615 47726 47744 47810 47844 47873 47897 47947 47949 47969 47973 48160</spatial><spectral>5.585776613014535e-25 5.585776613014535e-25</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/80/137?format=ascii</footprint><waveband>Radio</waveband></coverage><tableset><schema><name>default</name><table><name>J/ApJS/80/137/southext</name><description>Structure of Southern Extended Extragalactic Radio Sources</description><column><name>recno</name><description>Record number assigned by the VizieR team.
