AN ATLAS OF H-II REGIONS IN NEARBY SEYFERT-GALAXIES

Continuum-subtracted H alpha images of 17 nearby Seyfert galaxies are presented. The images are calibrated astrometrically using the Hubble Space Telescope Guide Star Catalog reference frame. For each galaxy, a n inventory of H II regions detected using the COSMOS image classifier and centroider is provided. Salient features of each galaxy are descr ibed, including the distribution of the H II regions with reference to the galaxy morphology. Relevant abundance data from the literature ar e noted for each object. These images will find use as finding charts for follow-up spectrophotometric investigations of abundances, abundan ce gradients, and kinematics of H II regions in active galaxies, and f or detailed studies of H II region populations in these objects.
