cds-question@unistra.frgalaxiesphotometryWe have studied the relationship between the star formation rate (SFR), surface density, and gas surface density in the spiral galaxy M51a (NGC 5194), using multiwavelength data obtained as part of the Spitzer Infrared Nearby Galaxies Survey (SINGS). We introduce a new SFR index based on a linear combination of Halpha emission-line and 24um continuum luminosities, which provides reliable extinction-corrected ionizing fluxes and SFR densities over a wide range of dust attenuations.2007ApJ...671..333Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/671/333CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/633/871 : Positions and photometry of HII knots in M51 (Calzetti+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/671/333https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/671/333http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/671/333https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/671/333https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/671/333http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/671/333GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/671/333/table1 (Aperture Photometry and SFR in NGC 5194)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/671/333/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/671/333/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/671/333/table1?GETtext/xml+votable180.050000true202.46458347.1952780.0055555555555555566/11027https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/671/333?format=asciiOpticaldefaultJ/ApJ/671/333/table1Aperture Photometry and SFR in NGC 5194recnoRecord number assigned by the VizieR team.
