CDROM/APJS/V105/P093 H II Regions in Nearby Seyfert Galaxies (Evans+ 1996) ================================================================================ An Atlas of H II Regions in Nearby Seyfert Galaxies I. N. Evans, A. P. Koratkar, T. Storchi-Bergmann, H. Kirkpatrick, T. M. Heckman, and A. S. Wilson <1996, ApJS, 105, 93> =1996ApJS..105...93E ================================================================================ Abstract: Continuum-subtracted Halpha 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, an inventory of H II regions detected using the COSMOS image classifier and centroider is provided. Salient features of each galaxy are described, including the distribution of the H II regions with reference to the galaxy morphology. Relevant abundance data from the literature are noted for each object. These images will find use as finding charts for follow-up spectrophotometric investigations of abundances, abundance gradients, and kinematics of H II regions in active galaxies, and for detailed studies of H II region populations in these objects.
