cds-question@unistra.frgalaxiesphotometryvisible-astronomyh-alpha-photometryradial-velocityA detailed kinematic analysis of ionized gas in the nearby irregular galaxy NGC 4449 is presented. Observations were conducted in the spectral lines of H{alpha} and [S II]. Our scanning Fabry-Perot interferometric observations are presented from both a global and a local perspective. We have analyzed the global velocity field, the spatially extended diffuse gaseous component, and the H II region populations and, furthermore, have determined the rotation curve based on the heliocentric radial velocities of the global H{alpha} spatial distribution.2002AJ....124.3157Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/124/3157CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/124/3157https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/124/3157http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/124/3157https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/124/3157https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/124/3157http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/124/3157GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/124/3157/table3Photometry for the H II regions in NGC 4449recnoRecord number assigned by the VizieR team.
