Stromlo Observatory from December 1957 to April 1959. The entire region of the Milky Way southward of the Palomar sky survey with a latitude of plus or minus 15 degrees of the galactic equator was photographed in the light of hydrogen alpha with comparison plates obtained in yellow light. This work roughly complements the Sharpless (Sh2, see Cat. &lt;VII/20&gt;) survey published in 1959.</description><source format="bibcode">1960MNRAS.121..103R</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/216</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/VII/20">VII/20 : Catalogue of HII Regions (Sharpless 1959)</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=VII/216</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VII/216</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VII/216</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=VII/216</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=VII/216</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=VII/216</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 VII/216/rcw (The Catalogue (tables 2 and 3 of the paper))</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/VII/216/rcw?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/VII/216/rcw?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/VII/216/rcw?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>107.5841</ra><dec>-12.0327</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>5/10756 6/20766 20784 20816 20849 21504 21510 21550 21638 21646 21655 21657 28734 28809 28817 28825 28827 28828 28829 28830 28833 28891 28900 28905 28913 28915 28917 28924 28925 29092 29093 29103 29110 29112 29115 29116 29119 29154 29162 29445 29451 29463 29467 29505 29513 29529 29534 29541 30218 30257 30268 30271 30329 30330 30341 30430 30449 30592 37232 37239 37244 37343 37362 37364 37366 37367 37708 37710 37752 37846 37850 37872 37875 37884 37886 37896 37899 37900 37924 37929 37961 38016 38017 38019 38026 39249 39254 39257 39266 39272 39278 39281 39283 39285 39289 39291 39375 39384 39748 39801 39804 39914 40033 40618 40619 41576 41587 41599 41655 41656 41664 41675 41677 41678 41681 41682 41688 41696 41758 41759 41760 41780 41782 41789 41792 41812 41813 41817 41820 41824 42154 42163 42168 42169 42212 42214 42229 42297 42377 42378 42391 42405 42434 42436 42439 42441 42445 42446 42447 42456 42457 42462 42464 42481 42505 42516 42753 42765 42948 43017 43021 43182</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/VII/216?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>VII/216/rcw</name><description>The Catalogue (tables 2 and 3 of the paper)</description><column><name>recno</name><description>Record number assigned by the VizieR team.
