To include the white dwarfs discovered since 1999 and to include the X-ray sources detected in ROSAT Position Sensitive Proportional Counter (PSPC, &lt;IX/30&gt;) observations made with a boron filter, we have carried out another search using an updated list of white dwarfs and the final catalogs of the ROSAT PSPC observations with and without a boron filter. Forty-seven new X-ray sources convincingly coincident with white dwarfs are found and reported in this paper.</description><source format="bibcode">2004AJ....127..477C</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/477</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/IX/31">IX/31 : The WGACAT version of ROSAT sources (White+ 2000)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/IX/30">IX/30 : Second ROSAT PSPC Catalog (ROSAT, 2000)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/IX/38">IX/38 : ROSAT Sources for the PSPC with filter (2RXF) (ROSAT Team, 2001)</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/AJ/127/477</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/477</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/477</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/477</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/477</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/477</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/AJ/127/477/table1 (White dwarfs coincident with ROSAT PSPC X-ray sources)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/477/table1?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/477/table1?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/477/table1?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>2.07375</ra><dec>51.3875</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/709 1283 2809 3693 5072 5434 5439 5569 5872 5898 5902 5936 6070 7267 7352 7498 8717 8908 9471 9832 9901 10959 11074 11339 11973 15287 16052 16886 20369 20940 22943 23101 23644 23789 25138 26851 27049 27934 27944 28129 28259 30406 34026 34197 34360 34515 34676 35759 36589 37592 43290 45782 45815 45909 46385 46695 47011 47100</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/477?format=ascii</footprint><waveband>X-ray</waveband></coverage><tableset><schema><name>default</name><table><name>J/AJ/127/477/table1</name><description>White dwarfs coincident with ROSAT PSPC X-ray sources</description><column><name>recno</name><description>Record number assigned by the VizieR team.
