Scientific paper

The paper presents the first set of data on 21 galaxies in five different clusters, obtained from 2D H-alpha observatons at the Canada-France-Hawaii Telescope equipped with a scanning Perot-Fabry interferometer. These galaxies are from the following clusters: Abell 539 (two galaxies), Cancer (six galaxies), Coma (six galaxies), Hercules (two galaxies), and Pegasus (five galaxies). Presented are H-alpha maps (continuum and line), velocity contour maps, and rotation curves of the 21 galaxies, together with the table of galaxies' parameters.
