Scientific paper

The paper presents high-resolution (35 km/s) spectroscopic observations of forbidden O III 4959/5007 A emission lines in 13 southern active galactic nuclei. Profile parameters are presented for each object, using the characterization methods defined by Heckman et al. and Whittle. The parameters are compared with measures from other authors, obtained with different resolutions and detectors. The paper also presents the very unusual forbidden O III 5007 A profile of NGC 7213, with two very distinct components, a narrow one being attributable to a 'classical' Narrow Line Region, and a very wide one which may originate in a region characteristic of LINERs.
