摘要

We present the results of tridimensional spectrophotometric observations of the central region of the Seyfert galaxy NGC 1068 obtained by using Kyoto tridimensional spectrograph I. A brief description of the instrument is presented. We have found the existence of low-ionized gas extending out of the ionization cone. It is characterized by higher ([S II]$\lambda6716+\lambda6731) / {\rm H}\alpha$ th...
