Monte-Carlo methods were used to simulate catalogues of positions and proper motions of quasars and galaxies to test the link. The main conclusion is, that future satellite missions like GAIA may be "self-calibrated" by their measurements of QSOs, while additional measurements from radio stars or HST-data are needed to calibrate the less deep reaching astrometric satellite missions of AMEX type.</description><source format="bibcode">2004A&amp;A...413..771M</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/413/771</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/I/259">I/259 : The Tycho-2 Catalogue (Hog+ 2000)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/VII/119">VII/119 : Catalogue of Principal Galaxies (PGC) (Paturel+ 1989)</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/413/771</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/413/771</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/413/771</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/413/771</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/413/771</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/413/771</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/413/771/table (Galaxies in the Tycho-2 Catalogue)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/413/771/table?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/413/771/table?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/413/771/table?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>40.84990833</ra><dec>1.75658528</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/2183 2260 2266 2346 2582 3073 3389 4038 4931 5157 5201 6012 6014 6361 7742 7923 7934 8004 8046 8072 8239 9507 9535 9830 10575 10597 10912 10973 11026 11195 11379 11394 11947 11950 12144 13509 13512 13906 16434 16480 16653 16675 17431 17462 17696 17726 17777 17780 18480 18764 18793 19877 19996 20531 20665 20712 20716 20883 21134 21140 21189 22610 22632 23180 23233 24599 24882 24893 24906 24936 25094 25136 25581 26175 26420 27138 27199 27217 27353 27422 27719 27743 27750 27936 28515 28538-28539 31642 32953 33034 33038 33151 33354 33650 33880 33971 34493 34554 34683 34736 34892 35080 35319 35409 35541 35635 36039 36107 36151 36172 36261 37119 37434 37541 37637 38309 38467 38475 38493 38515 38518 38620 38648 38657 38702 38755 38888 39108 40165 40247 40252 40302 40337 40527 40910 40966 41112 41245 41425 42030 42032 43305 43330 43473 43627 43732 43763 43827 43830 43885 43996 44052 44166 45091 45131 45426 45523 45636 45700 45721 45981 45984 46133 46327 46438 46507 46562 46834 46984 47001 47308 47415 47435 47630 47715 48007 48154 48520 48544</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/413/771?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/A+A/413/771/table</name><description>Galaxies in the Tycho-2 Catalogue</description><column><name>recno</name><description>Record number assigned by the VizieR team.
