The nearer reflection nebulae lie predominantly along Gould's Belt, whereas the more distant ones are concentrated to the galactic plane. The data outline 13 associations of reflection nebulae, some of which coincide with known OB or T associations. Attention is drawn to the fact that most reflection nebulae are illuminated by the integrated light of the Milky Way. The integrated radiation will be more intense above and below the galactic plane then in the galactic plane where the nuclear bulge of the Galaxy and most of the disk are obscured by interstellar absorption.</description><source format="bibcode">1966AJ.....71..990V</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/21</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=VII/21</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VII/21</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VII/21</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=VII/21</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=VII/21</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=VII/21</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/21/catalog (The catalogue (Table I of publication) (corrected version, 13-Nov-2022))</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/VII/21/catalog?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/VII/21/catalog?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/VII/21/catalog?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>2.6931914</ra><dec>58.7695183</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/342 463 474 856 862 881 1064 1114 1125 1169 1285 1293 1460 1539 1583 1591 3005 3030 3038 3183 3198 3284 3293 3430 3634 3752 3766 3842 3849 12964 13235 13721 13786 13895 14031 14055 14347 14431 14621 14646 14700 14704 14807 15396-15397 15449 15478 15568 15617 15668 15677 15683 15759 15790 15800 15842 15850 15856 16131 16193 20745 21285 21337 21354 21400 21403 21428 21436-21437 21447 21456 21458 21465 21510 21640-21641 21643-21644 21646 21667 21671 22209 22787 22804 22807 22829 22854-22855 22861 22863 22873 22911 23007 23451 23560 23591 23621 23641 23644 23688 23714 23763 23998 24076-24077 24132 24189 24273 24427 24499 28894 28917 29092 29102-29103 29113-29114 29244 29359 29505 29522 29668 30014 30366 30706 31217 36102 39896 39916 42956 42959 42977 42981 42994 44305 44371 44378</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/VII/21?format=ascii</footprint></coverage><tableset><schema><name>default</name><table><name>VII/21/catalog</name><description>The catalogue (Table I of publication) (corrected version, 13-Nov-2022)</description><column><name>recno</name><description>Record number assigned by the VizieR team.
