摘要
Observations of seven objects selected from the de Grijp et al. Catalog of AGN candidates (A&AS, 70, 95, 1987) and two from the list of Maia et al. (AJ, 93, 546, 1987) are reported. From their optical spectral characteristics they are classified according to their degree of nuclear activity: two of them as Seyfert 2 types, two others as Seyfert 1.9 types, one as a LINER, and three as H II region-like galaxies; the remaining one turns out to be a star. Far-infrared properties are also used to analyze these objects. Very good correlations between the far-IR luminosity and Ha and [O III] lambda 5007 luminosities are found for the Seyfert galaxies. The far-infrared luminosity of these seems to depend on both, the amount of the dust present and strongly on the number of ionizing photons.
