We take advantage of the spatial resolution (2.5-arcsec full width at half-maximum) of the Swift/Ultraviolet/Optical Telescope camera and the availability of three ultraviolet (UV) passbands in the region 1600<{lambda}<3000{AA}, in combination with optical and infrared (IR) imaging from Sloan Digital Sky Survey, KPNO/H{alpha} and Spitzer/IRAC, to obtain a catalogue of 787 star-forming regions out to three disc scalelengths. We use a large volume of star formation histories, combined with stellar population synthesis, to determine the properties of the young stellar component and its relationship with the spiral arms.2012MNRAS.424.1636Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/424/1636CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/297/255 : HII region catalogue of M100 (Knapen, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/424/1636https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/424/1636http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/424/1636https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/424/1636https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/424/1636http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/424/1636GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/424/1636/catalog (Catalogue of UVW2 sources in NGC4321 (M100) (tables 2 and 3 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/424/1636/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/424/1636/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/424/1636/catalog?GETtext/xml+votable180.050000true185.727290615.82107330.0055555555555555566/28033 280352.0616683193919197e-20 1.2058628298368645e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/424/1636?format=asciiUVOpticalRadiodefaultJ/MNRAS/424/1636/catalogCatalogue of UVW2 sources in NGC4321 (M100) (tables 2 and 3 of the paper)recnoRecord number assigned by the VizieR team.
