cds-question@unistra.frthe-sunmagnetic-fieldsThe area asymmetry between the preceding and following regions of opposite magnetic polarity in a bipolar sunspot group has been known since the studies of Hale and his colleagues in the early 20th century. This area asymmetry, however, has not yet been investigated quantitatively using magnetograms. We quantitatively define the area asymmetry of bipolar magnetic fields in the photosphere of active regions on the Sun, and investigate correlations between the area asymmetry and other parameters.2012A&A...539A..13Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/539/A13CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJS/169/439 : Models of solar magnetic structures (Socas-Navarro, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/539/A13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/539/A13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/539/A13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/539/A13https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/539/A13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/539/A13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/539/A13/table3Bipolar regionsrecnoRecord number assigned by the VizieR team.
