Scientific paper
The Seyfert 1 galaxy NGC 4151 will be studied in several ways. 1} Low-resolution spectra over the entire UV and visible range will be obtained through a slit at several different orientations to model the physical conditions in the emission-line regions; 2} slitless spectra of strong emission lines at moderate resolution and narrow-band WFPC2 images will be used to map the dynamics of the regions; 3}echelle spectra over the entire UV bandpass will be used to study the intrinsic absorption in the nucleus; and 4} parallel imaging will be performed of the outer galaxy and other galaxies or QSOs.
