Description
High-dispersion [OIII] profiles of 42 Southern hemisphere active and HII galaxies are presented as the first part of a study of the Narrow Line Region of active galaxies. A parameter scheme based on area measurements is defined which characterizes the width, asymmetry and kurtosis of different parts of the profile. Techniques for estimating errors and resolution corrections are described. A comparison with parameters defined by a cut at constant height shows the area parameters to be less sensitive to noise, more stable to the effects of poor resolution and more sensitive to information contained in the base and wings of the profile.
