H-alpha velocity fields and rotation curve of galaxies in clusters.
Abstract
Hα maps (continuum and line), velocity contour maps and rotation curves are presented for 21 galaxies in five different clusters: Pegasus I, Cancer, Coma (A1656), Abell 539, and Hercules (A2151). These data have been obtained from two-dimensional Hα observations at the Canada-France-Hawaii Telescope equipped with PALILA, a scanning Perot-Fabry interferometer.
