cds-question@unistra.frgalaxy-clustersh-ii-regionsspectroscopyradial-velocityWe have obtained spectra of HII regions in the heavily obscured spiral galaxy Maffei 2. The observations have allowed for a determination of the Galactic extinction of this galaxy using a correlation between extinction and hydrogen column density observed among spiral galaxies.2007ApJ...655..814Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/655/814CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/124/559 : VI photometry of dwarf galaxies (Karanchentsev+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/655/814https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/655/814http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/655/814https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/655/814https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/655/814http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/655/814GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/655/814/table3 (Properties of the spiral galaxies hosting HII regions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/655/814/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/655/814/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/655/814/table3?GETtext/xml+votable180.050000true143.04041721.5005560.005555555555555556Cone search capability for table J/ApJ/655/814/h2reg (Properties of HII Regions in Maffei 2, IC 342 and Sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/655/814/h2reg?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/655/814/h2reg?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/655/814/h2reg?GETtext/xml+votable180.050000true40.452083359.59055560.0055555555555555566/2154 2155 2241 3299 3506 3507 4511 7743 10841 11027 11434 26303 27918 27945 28033 28035https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/655/814?format=asciiOpticaldefaultJ/ApJ/655/814/table3Properties of the spiral galaxies hosting HII regionsrecnoRecord number assigned by the VizieR team.
