New photometric observations were made on 13 nights at the Ankara University Observatory (AUO) in 1997/1998 by using a 30cm Cassegrain-Maksutov telescope. The detector was a single-channel, uncooled SSP-5 photometer equipped with Hamamatsu R1414 photomultiplier tube. Observational standard errors determined from check star (HD 35633 = SAO 58053) measurements are 0.014mag, 0.012mag, and 0.018mag in U, B, and V filters, respectively. A total of 966, 959, 947 original data and of 118, 117, 117 reduced (averaged) data points is included for each UBV filters, respectively.</description><source format="bibcode">2003A&amp;A...403..675O</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/403/675</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic 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/403/675</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/403/675</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/403/675</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/403/675</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/403/675</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/403/675</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><coverage><footprint ivo-id="ivo://ivoa.net/std/moc"/><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>J/A+A/403/675/vmag</name><description>Photometric data of IU Aur in V filter</description><column><name>recno</name><description>Record number assigned by the VizieR team.
