cds-question@unistra.frgalaxy-rotationradial-velocityHigh resolution Fabry-Perot data of six spiral galaxies are presented. Those data extend the previous sample of spiral galaxies studied with high resolution 3-D spectroscopy to earlier morphological types. All the galaxies in the sample have available HI data at 21cm from the VLA or Westerbork. Velocity fields are analyzed and H{alpha} rotation curves are computed and compared to HI curves. The kinematics of NGC 5055 central regions are looked at more closely. Its peculiar kinematics can be interpreted either as a bipolar outflow or as a counter-rotating disk, possibly hosting a 9+/-2x10^8^M_{sun}-compact object. Most of the H{alpha} rotation curves present a significantly steeper inner slope than their HI counterparts. The 21cm data thus seems affected by moderate to strong beam smearing. The beam smearing has an effect at higher scale-length/beam-width than previously thought (up to 20km/s at a ratio of 8.5).2004A&A...420..147Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/420/147CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/420/147https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/420/147http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/420/147https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/420/147https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/420/147http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/420/147GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/420/147/tablea2Optical rotation curve of NGC 2403 at 6.6" resolutionrecnoRecord number assigned by the VizieR team.
