Abstract

Two-dimensional spectroscopy of the central 24'' × 20'' of the Seyfert 2 galaxy NGC 1068 has been obtained using a fiber-optic system (2D-FIS). The homogeneity, spectral coverage (~4170-5749 and 6250-9469 A), and spatial (~09) and spectral resolution (~1.53 A pixel-1 and 2.73 A pixel-1) of the data make them a useful database with which to study in detail the kinematics and physical properties of the circumnuclear region of this galaxy, as well as the active nucleus and host galaxy connection. The data are presented as an atlas containing 570 spectra, which include over 15 emission lines and several stellar features. We have carried out a preliminary analysis of the data, deriving continua at different wavelengths and emission-line intensity maps directly from the observed spectra. We have also derived the ionized velocity field from different emission lines, and the stellar velocity field. Velocity dispersions of the stellar component have also been estimated.
