Abstract | High signal-to-noise ratio spectra were obtained of nearly all the Seyfert 2 galaxies in the CfA complete sample published by Huchra & Burg, and of some of the Seyfert 1's as well. Several of the Seyfert 2 galaxies have weak, broad components to their Hα emission lines, and in some cases to Hβ as well, and thus are Seyfert 1.8 or 1.9 objects on the Lick Observatory classfication system.
