cds-question@unistra.frgalaxiesvisible-astronomyh-ii-regionssurveysAn H-alpha survey, using a focal reducer and narrow-band interference filters, has resulted in the detection of nearly a thousand HII regions in M31. The catalog gives their positions, dimensions, and surface brightnesses. The surface brightnesses are on an absolute scale; the photographic measures were calibrated by using photoelectric measures from two different sources. The detection limit reached corresponds to an emission measure of 40cm^-6^pc at a temperature of 10000K.1978A&AS...31..439Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/31/439CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/31/439https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/31/439http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/31/439https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/31/439https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/31/439http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/31/439GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/31/439/table1 (HII regions in M31)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/31/439/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/31/439/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/31/439/table1?GETtext/xml+votable180.050000true9.91890140.2185010.0055555555555555566/2622-2623 2666 2708-2709 2752https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/31/439?format=asciiOpticaldefaultJ/A+AS/31/439/table1HII regions in M31recnoRecord number assigned by the VizieR team.
