Analysis of their accuracy is made by comparison with the Hipparcos catalogue (Perryman et al., 1997, Vat. &lt;I/239&gt;) and astrometric catalogue of radio stars in the radio window from the article of Walter et al. (1990A&amp;AS...86..357W).</description><source format="bibcode">2001A&amp;A...375..670R</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/375/670</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+A/375/670</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/375/670</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/375/670</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/375/670</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/375/670</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/375/670</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+A/375/670/table2 (Photographic coordinates of 113 Radio Sources)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/375/670/table2?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/375/670/table2?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/375/670/table2?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>0.85102917</ra><dec>55.68264722</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/15 342 845 1399 1704 1922 2062 2990 3054 3283 3307-3308 3430 4365 4444 4735 5627 6241 7684 8440 8737 8926 10255 10305 11543 11959 12155 12551 12852 12888 13055 13207 13286 13743 13778 13845 13875 13933 13947 14078 14238 14279-14280 14632 14646 14649 14692 14727 14788 14855 15385 15749 16459 17058 17192 17716 18309 18889 19556 20102 20286 20764 21069 21530 21536 21694 21731 22289 22625 22680 22707 22854 22862 22904 23086 23191 23451 23611 23767 24228 24554 25544 26070 26327 27731 29009 29505 29507 29734 29906 30389 30506 30606 30615 30626 30684 30687 30833 31774 31984 32173 36526 39905 40131 44658 48587 48737</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/375/670?format=ascii</footprint><waveband>Radio</waveband></coverage><tableset><schema><name>default</name><table><name>J/A+A/375/670/table2</name><description>Photographic coordinates of 113 Radio Sources</description><column><name>recno</name><description>Record number assigned by the VizieR team.
