Visit NGC 3783 three times line_2: and NGC 3516 twice. Each target will be observed using grating 160M at two line_3: settings. The two grating settings must be scheduled during a single line_4: visit. The visits for each target should be separated by at least 6 months. line_5: The three observations of NGC 3783 should therefore cover at least 18 line_6: months. More explicitly, line numbers 62 - 65 in this proposal should line_7: follow line numbers 50 - 52 in proposal 1160 (the cycle 1 proposal) line_8: by 9 months +/- 3 months. If target acquisitions are trivial on revisits, line_9: reallocate the time allotted to target acquisition so as to prolong the line_10: spectral exposures. ! ! end of abstract general_form_proposers: lname: BRANDT fname: JOHN mi: C. inst: COLORADO, UNIVERSITY OF country: USA ! lname: WEYMANN fname: RAY mi: J. inst: MT.

Visit NGC 3783 three times line_2: and NGC 3516 twice. Each target will be observed using grating 160M at two line_3: settings. The two grating settings must be scheduled during a single visit. line_4: Target acquisitions will be done using the BRIGHT=RETURN option starting in line_5: cycle 2 (when it becomes available). Acquisition peakups will be done as a line_6: part of each acquisition. For each observation with each grating setting, line_7: each target will be observed using FP_SPLIT=4 and quarter-stepping. Each line_8: individual FP-SPLIT will be no longer than about 20 minutes, to minimize line_9: drifting caused by the geomagnetic field. The FP-SPLITs will be repeated line_10: until the desired exposure times are obtained. line_11: The visits for each target should be separated by at least 6 months. line_12: The three observations of NGC 3783 should therefore cover at least 18 line_13: months. If target acquisitions are trivial on revisits, reallocate the time line_14: allotted to target acquisition so as to prolong the spectral exposures. ! question: 4 section: 1 line_1: The lines of interest for this investigation are in the UV and must be observed line_2: from space. Only the HRS, operating on the ST, has sufficient sensitivity and line_3: photometric accuracy to accomplish the required observations. ! question: 5 section: 1 line_1: Scheduling requirements are imposed to ensure that two settings for G160M line_2: are scheduled for each visit, because the emission line fluxes and profiles line_3: are potentially highly variable on short timescales. Separate visits of a line_4: single target are required to be separated by at least 6 months, to ensure line_5: that the absorbing clouds will have had sufficient time to vary in their line_6: geometry, physical properties, and kinematics. line_7: THIS PROGRAM NO LONGER REQUIRES THAT THE GC/OST CAPABILITY OF line_8: THE GHRS BE IMPLEMENTED. ! question: 6 section: 1 line_1: Scheduling requirements are imposed to ensure that target acquisition is line_2: done during dark time, because the targets are variable and may be faint line_3: compared to the background at other times. ! question: 7 section: 1 line_1: The data will be analyzed with the SDAS to determine wavelengths, line line_2: profiles, etc. We will also consider analyzing the data with institutional line_3: facilities at GSFC. ! question: 8 section: 1 line_1: We will attempt to arrange correlated observations with optical and radio line_2: telescopes (also X-ray observations, if feasible) once the HST schedule has line_3: been established. ! question: 10 section: 1 line_1: This research will be supported through the post-launch science budget of the line_2: HRS Science Team. GSFC will provide the services of the GSFC-employed line_3: investigators as well as support through miscellaneous institutional facilities line_4: and services. ! question: 13 section: 1 line_1: Investigation of the properties of broad line clouds in X-ray selected low line_2: luminosity Seyfert galaxies as manifested in C IV. Determination of line_3: covering fraction, column density, and other properties of the absorbing line_4: clouds. ! !end of general form text general_form_address: lname: SMITH fname: ANDREW mi: M. inst: NASA, GODDARD SPACE FLIGHT CENTER addr_1: CODE 681 city: GREENBELT state: MD zip: 20771 country: USA phone: (301) 344-8648 ! lname: MUSHOTZKY fname: RICHARD mi: F. inst: NASA, GODDDARD SPACE FLIGHT CENTER addr_1: CODE 661 city: GREENBELT state: MD zip: 20771 country: USA phone: (301) 286-3900 ! lname: MARAN fname: STEPHEN mi: P. title: DR. category: PI inst: NASA, GODDARD SPACE FLIGHT CENTER addr_1: CODE 680 city: GREENBELT state: MD zip: 20771 country: USA phone: (301) 286-8607 ! lname: WEYMANN fname: RAY mi: J. inst: MT.
