Abstract

Using 1-20 micron ground-based IR observations, 100 and 60 micron IRAS fluxes and optical UBVR photometry, continua for a sample of 37 Seyfert 1 galaxies are found to be simply classified in three families by means of IR (60 micron/12 micron) and optical (1.2 micron/0.3 micron) colors. Class A galaxies are found to be nonreddened and to present no significant amount of cool dust or galaxy IRAS component, while Class B galaxies are reddened AGN. Class C galaxies are shown to be both reddened and contain large galaxy disk cool dust components.
