We found 521 DAs with detectable Zeeman splittings, with fields in the range from around 1 to 733MG, which amounts to 4% of all DAs observed. As the SDSS spectra have low signal-to-noise ratios, we carefully investigated by simulations with theoretical spectra how reliable our detection of magnetic field was. 2013MNRAS.429.2934K https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/429/2934 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/A+A/506/1341 : Magnetic fields in white dwarfs (Kuelebi+, 2009) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/429/2934 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/429/2934 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/429/2934 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/429/2934 https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/429/2934 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/429/2934 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/MNRAS/429/2934/table1 (Magnetic white dwarf stars) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/429/2934/table1? https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/429/2934/table1? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/429/2934/table1?
