These classifications are shown to be on the MK system. Two sources of area scanner UBV photometry were compared in order to establish homogeneous photometric as well as spectroscopic data. From a consideration of systematic errors in the V magnitude difference between components the photometry of Hurly and Warner is to be preferred. Absolute magnitudes for each binary are derived from magnitude difference via a tested MK-Mv map.</description><source format="bibcode">1984ApJS...55..657C</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/III/117</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=III/117</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=III/117</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=III/117</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=III/117</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=III/117</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=III/117</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 III/117/tables (Tables 1A and 1B from the published paper)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/III/117/tables?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/III/117/tables?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/III/117/tables?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>2.3377789</ra><dec>-27.9879256</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/16495 16524 16587 16610 16665 20673 20696 21017 22637 24576 24604 24707 24743 28692 28735 28771 28808 28822 29196 32792 33225 33340 33430 33498 33625 33922 33930 33943 34284 34300 34496 34509 34536 34607 34832 34839 34896 34907 35564 35788 35796 35842 35878 35948 36018 37169 37214 37297 37314 37427 37452 37497 37664 37677 37765 37826 37832 37902 38049 38137 38191 38243 38440 38441 38452 38561 38619 38719 38936 38941 38957 39023 39189 39243 39275 39279 39281 39288 39294 39316 39373 39423 39443 39464 39498 39562 39625 39679 39691 39720 39740 39744 39808 40014 40018 41167 41393 41446 41478 41580 41607 41630 41711 41858 41943 41957 42053 42071 42189 42285 42291 42430 42444 42459 42605 42640 42645 42684 42719 42808 42886 42903 42932 42956 43008 43014 43016 43093 43097 43286 43368 43540 43651 43652 43674 43797 43843 43856 43975 44049 44196 44258 44306 44435 45086 45505 45602 45835 45927 46203 46299 46320 46366 46510 46563 46744 46915 46918 47021 47140 47568 47742 47777 47879 48076 48254 48299 48359</spatial><spectral>3.322582951404819e-19 3.852589004194616e-19</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/III/117?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>III/117/notes</name><description>Notes to tables</description><column><name>recno</name><description>Record number assigned by the VizieR team.
