We use the catalog to search for magnetic white dwarfs in cataclysmic variable progenitor systems. Given that approximately 25% of cataclysmic variables contain a magnetic white dwarf, and that our large sample of close binary systems should contain many progenitors of cataclysmic variables, it is quite surprising that we find only two potential magnetic white dwarfs in this sample. 2007AJ....134..741S https://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/741 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/276 : The SDSS Photometric Catalog, Release 5 (Adelman-McCarthy+, 2007) III/70 : Luyten's White Dwarf Catalogues (Luyten, 1970-77) J/AJ/124/1118 : High-velocity white dwarfs radial velocities (Silvestri+ 2002) J/ApJ/586/1356 : White dwarfs with cool companions (Wachter+, 2003) J/AJ/126/1023 : White Dwarfs in the SDSS (Harris+, 2003) J/ApJ/607/426 : Catalog of white dwarfs in SDSS-DR1 (Kleinman+, 2004) J/AJ/129/2428 : M dwarf-white dwarf binary systems (Silvestri+, 2005) J/AJ/131/582 : Cool white dwarfs in the SDSS (Kilic+, 2006) J/AJ/131/1674 : Close binary systems from SDSS DR4 (Silvestri+, 2006) http://www.sdss.org : SDSS Home Page https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/741 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/741 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/741 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/741 https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/741 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/741 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/AJ/134/741/table1 (The SDSS-I DR5 catalog of close binary systems) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/741/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/741/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/741/table1?
