Variability studies of Seyfert galaxies - II. Spectroscopy.
Abstract
Spectroscopic observations of 36 southern Seyferts are presented. Most of these also have been monitored photometrically over a period of four years (Winkler et al). The objects are classified, line fluxes and widths are measured and peculiarities of the spectra are discussed. Many of the objects have been observed more than once and changes in the line strengths and profiles are examined. Comparisons are also made with the spectra published by other investigators.
