Abstract

We present preliminary results about the velocity field of the ionized gas in the central region of NGC 1068, inferred from the [O III] λλ4959, 5007 emission lines. The data, 570 spectra in the inner 23″ × 18″ of this galaxy, were obtained with an optical fiber system which allows 2-D spectroscopy. The velocity field for the ionized gas inferred from the [O III] lines is in good agreement with recent results based on the Hα+[N II] lines.
