2003A&A...399...51G GHASP: An H{alpha} kinematic survey of spiral and irregular galaxies II. Velocity fields and rotation curves of 15 galaxies O. Garrido - M. Marcelin - P. Amram - O. Boissin Observatoire Astronomique Marseille-Provence & Laboratoire d'Astrophysique de Marseille, 2 place Le Verrier, 13248 Marseille Cedex 04, France Received 8 August 2002 / Accepted 19 November 2002 Abstract. We present Fabry-Perot images obtained during the GHASP survey (Gassendi H{alpha} survey of SPirals). We have derived the H{alpha} maps, the 2D velocity fields and the rotation curves for a new set of 15 galaxies, increasing the sample we plan to build. The majority of the objects studied here are late-type spirals (Sc-Sdm) and irregular galaxies. Only 8 galaxies have a regular and symmetric rotation curve (two of them have a solid-body rotation curve) and they are all of morphological type earlier than 8 ~ Sd. Five galaxies present an irregular rotation curve and they are all very late-type galaxies (t >= 8.8). For one galaxy, UGC 2053, no rotation curve could be derived, and for another one, UGC 11300, both sides have completely different behaviors. All of them have already been observed in HI by the WHISP survey led at Westerbork, for which GHASP brings an interesting complement. Key words: galaxies: kinematics and dynamics - galaxies: spiral - galaxies: irregular - galaxies: dwarf
