We will concentrate line_3: on Seyfert 2 galaxies in order to avoid possible confusion with the spectrum of line_4: the broad line region (BLR). We wish to use a wide variety of the HST line_5: instruments, to insure that a comprehensive and high-quality data set is built line_6: up for a representative sample of nearby Seyfert 2 galaxies. These data should line_7: immediately allow us to address several important, inter-related questions line_8: about AGN: line_9: a. What is the velocity field in the innermost part of the NLR? line_10: b. Where does the reddening occur in AGN? line_11: c. What is the chemical composition of the gas associated with the AGN? line_12: d. How do the Seyfert 1 and Seyfert 2 continuum sources differ? line_13: e. Do most Seyfert 2 galaxies contain "hidden" BLRs? line_14: We will exploit both the high UV response and high spatial resolution of line_15: HST, using PC images to map out the NLR structure in a few strong lines, FOS line_16: and HRS to obtain detailed nuclear spectra over a wide wavelength range, and line_17: most importantly, FOC in its long slit mode to study spatial variations in the line_18: UV and optical spectra. ! ! end of abstract general_form_proposers: lname: FERLAND fname: GARY title: DR. mi: J. inst: OHIO STATE UNIVERSITY country: USA ! lname: WILLS fname: BEVERLEY title: PROF. mi: J. inst: TEXAS, UNIVERSITY OF country: USA ! lname: WILLS fname: DEREK title: PROF. inst: TEXAS, UNIVERSITY OF country: USA ! lname: NETZER fname: H. title: PROF. inst: TEL AVIV UNIVERSITY country: ISRAEL ! lname: BALDWIN fname: JACK title: P.I. mi: A. inst: CTIO country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Our goal is to make a comprehensive study of the Narrow Lined Region (NLR) of line_2: the seyfert galaxy NGC3393. Specifically, we were awarded HST time to try to line_3: answer the questions: line_5: a. What is the velocity field in the innermost part of the NLR? line_6: b. Where does the reddening occur in AGN? line_7: c. What is the chemical composition of the gas associated with the AGN? line_8: d. How do the Seyfert 1 and Seyfert 2 continuum sources differ? line_9: e. Do most Seyfert 2 galaxies contain "hidden" BLRs? line_11: Following our reassesment to take account of the spherical aberration problem, line_12: we had planned to use WFC, PC, FOS, and GHRS. The GHRS observations were line_13: requested on the expectation that most of the NLR emission would come from a line_14: nearly unresolved source coincident with the continuum nucleus, and that the line_15: best way to differentiate between general inflow or outflow in the NLR line_16: therefore would be to use high spectral resolution (e.g. GHRS) to look for line_17: asymmetries in the Ly-alpha emission profile. ! question: 3 section: 2 line_1: However, we now have obtained a series of short early acquisition exposures line_2: with WFC and PC. These very clearly show that the NLR emission comes from two line_3: regions which straddle the nucleus. There is no NLR emission from the nucleus line_4: itself. We therefore wish to abandon the GHRS observations, since they won't line_5: tell us anything, and instead use that spacecraft time to (1) take further PC line_6: exposures (in order to study this newly-discovered morphology at higher line_7: signal:noise), and (2) take FOS spectra of the brightest emission-line knot line_8: and also of the nuclear continuum source (since what we had previously thought line_9: was one target is now two targets). line_11: This revised observing plan will fit into exactly the same number of line_12: spacecraft hours as our previous (approved) observing plan, and will answer line_13: the exact same scientific questions that we were awarded HST time to answer. line_14: The change is needed in order to take into account what has been learned line_15: from the early acquisition exposures. ! question: 5 section: 1 line_1: The PC exposure times on lines 13-15 may be adjusted to make best use of line_2: spacecraft time. We are interested only in obtaining the total amount of line_3: exposure time specified for each filter, split into approximately the line_4: number of exposures indicated and avoiding very short exposures which would line_5: add only read noise. line_7: The WFC exposures on line 16, through filter F230W, should be taken just line_8: after a WFC decontamination. There is no need for them to be taken at the line_9: time as the images on lines 12-15, and in fact we would much prefer line_10: not to delay taking the other images just to wait for a decontamination. line_12: Accurate positions for the targets 3, 4 and 5 should be measured very soon line_13: now from existing PC images.
