| Abstract: |
We have analyzed Hα Fabry-Perot interferograms, as well as images on Hα, [S II], [N II] and [O III] of the flocculent Sd galaxy NGC 7793. A Catalogue of H II regions listing position, diameter and Hα flux is presented. Maps of ratios [S II]/Hα, [N II]/Hα, and [O III]/Hα are also discussed. Using the kinematical information, we determined the rotation curve of this galaxy. |
