Scientific paper

WF/PC narrow band images will be used to isolate ionized gas clouds near the nuclei and to look for organized structure such as disks, bubbles and jets. FOS spectrophotometry from 1200A to 7000A will be used to establish density, temperatures, chemical composition, ionization mechanisms, and reddening in the emission regions near the nucleus. Line profiles and radial velocities will be used to investigate broadening mechanisms such as turbulence, gas flows, and rotation. Small aperture spectra of the nucleus will be used to look for a photoionizing continuum and for line broadening in the nucleus, and will be used to establish physical conditions and dynamics of the nuclear gas. UV absorption lines will be searched for in the nuclear continuum in order to measure the amount and distribution of gas along the line-of-sight through the parent galaxy.
