CDROM/APJS/V101/P287 H II Regions in Seyfert Galaxies. I. (Tsvetanov+ 1995) ================================================================================ H II Region Populations in Seyfert Galaxies. I. Database Zlatan I. Tsvetanov and Artashes R. Petrosian <1995, ApJS, 101, 287> =1995ApJS..101..287T ================================================================================ Abstract: Data on positions, effective diameters, and absolute fluxes of H II regions on 21 Seyfert spiral galaxies are presented together with the Halpha + [N II] images and identification charts. The objects are selected from a larger emission-line survey of a distance-limited sample of southern Seyfert galaxies. Statistical analysis of the data as well as discussion and comparison of the H II region populations in Seyfert and normal galaxies will be presented in forthcoming papers.

The coordinate systems are centered on the nuclei of the galaxies, which are determined as the brightest point in Halpha. The X-axis is along the east-west direction, with negative values to the east, and the Y-axis is along the north-south direction, with negative values to the south. -------------------------------------------------------------------------------- ================================================================================ (End) Lee Brotzman [ADS] 23-Apr-96
