cds-question@unistra.frgalaxiesphotometryh-ii-regionsultraviolet-astronomyline-intensitiesThe nearby barred spiral NGC 2903 has an active starburst at its centre and HII regions distributed along its bar. We analyse the star-formation properties in the bar region of NGC 2903 and study its links to the typical bar morphological features. We combine space and ground-based data from the far-ultraviolet to the sub-millimeter spectral ranges to create a panchromatic view of the NGC 2903 bar. We produce two catalogues: one for the current star-formation regions, as traced by the H{alpha} compact emission, and a second for the ultraviolet (UV) emitting knots, containing positions and luminosities. From them, we obtain ultraviolet colours, star-formation rates, dust attenuation, and H{alpha} EWs, and analyse their spatial distribution. We estimate stellar cluster ages using stellar population synthesis models (Starburst99).2010A&A...521A...8Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/521/A8CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/396/2295 : Stellar cluster dynamical masses in NGC2903 (Hagele+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/521/A8https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/521/A8http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/521/A8https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/521/A8https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/521/A8http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/521/A8GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/521/A8/table2 (HII region catalogue of the bar zone of NGC 2903)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/521/A8/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/521/A8/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/521/A8/table2?GETtext/xml+votable180.050000true143.051458321.51796110.005555555555555556Cone search capability for table J/A+A/521/A8/table3 (Summary of positions and photometry of the star-forming knots)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/521/A8/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/521/A8/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/521/A8/table3?GETtext/xml+votable180.050000true143.04862521.51133330.0055555555555555566/4511https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/521/A8?format=asciiUVOpticaldefaultJ/A+A/521/A8/table2HII region catalogue of the bar zone of NGC 2903RAJ2000Right ascension (J2000)pos.eq.ra;meta.mainrecnoRecord number assigned by the VizieR team.
