Surface brightness distributions in Seyfert galaxies. I. The sample. Results of scanning.
Abstract
A sample of 45 spiral galaxies including 19 Seyfert objects is formed within distances less than 100 Mpc (H0 = 75 km s-1Mpc-1). Small aperture measurements in B with a scanning photoelectric photometer were made to obtain the surface brightness distributions along the major axes in 14 galaxies. The characteristic parameters such as the surface brightness and its gradient at the distance of 1 kpc from the center of galaxies are calculated.
