| Abstract | Data now available for 71 Seyfert galaxies are summarized and discussed. A collection of 37 spectra is presented to illustrate the spectral characteristics of these galaxies, and new UBV data are included for 18 galaxies. A well-defined angular-diameter-redshift relation is found to exist for the total sample of galaxies, so it is concluded that the redshifts are cosmological. The mean ultraviolet magnitude for 40 Se ... |
