The resulting line_6: models produce real spectra at a resolution of 0.25A. The use line_7: of this powerful new tool, in conjuntion with ~ 3A resolution line_8: data from the FOS and complementary ground-based data, will line_9: place strong constraints on the stellar ages and the star line_10: formation history in the knots. ! ! end of abstract general_form_proposers: lname: BRUHWEILER fname: FREDERICK title: DR. inst: CATHOLIC UNIVERSITY OF AMERICA country: USA esa: N ! lname: HUTCHINGS fname: JOHN title: DR. inst: DOMINION ASTROPHYSICAL OBS. country: CANADA esa: N ! lname: SMITH fname: ANDREW title: DR. inst: NASA/GODDARD SPACE FLIGHT CENTER country: USA esa: N ! lname: LANDSMAN fname: WAYNE title: DR. inst: STX CORPORATION country: USA esa: N ! lname: HOME fname: ALLEN title: MR. inst: CATHOLIC UNIVERSITY OF AMERICA country: USA esa: N ! lname: EBBETS fname: DENNIS title: DR. inst: BALL AEROSPACE GROUP country: USA esa: N ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Target Acquisition Scenario: AN EARLY ACQuisition using the line_2: WF/PC is required to determine accurate positions for knots. line_3: The imagery will be acquired using the F336W filter. line_4: FOS Spectra: The FOS spectra will be obtained through 4.3x4.3 line_5: aperture for two targets (knot 1 and 4). Both G130H and G190H line_6: observations will be made for these targets (A total of 4 line_7: FOS exposures). ! question: 4 section: 1 line_1: The PI has already investigated the bright knots of NGC 1068 line_2: using the IUE. These results, form the the foundation of this line_3: proposal. Although we obtained reasonable results, better S/N line_4: data are needed to constrain age estimates for stars in the line_5: knots. This can only be done using HST. ! question: 5 section: 1 line_1: We require an assisted early acquisition using the WF/PC. line_2: This is needed to provide better coordinates for the knots. ! question: 6 section: 1 line_1: N/A ! question: 7 section: 1 line_1: Data will be reduced and analyzed using software at either line_2: NASA/GSFC or CUA that has already been developed. line_3: Resulting spectra will be compared with computed population line_4: synthesis models. Spectra obtained at DAO and KPNO will be line_5: combined to constrain older, luminous stars populations. ! question: 8 section: 1 line_1: The HST observations are supported by ground-based line_2: observations at the Kitt Peak National Observatory line_3: and Dominion Astrophysical Observatory. ! question: 9 section: 1 line_1: 3031 (ERO) - unrelated line_2: 3024 (SAT) - unrelated line_3: 3021 (SAT) - related line_4: 1171 (cycle0) - unrelated line_5: 1172 (cycle0) - related line_6: In these programs, the PI was a Co-Investigator. The PI is line_7: also involved in severeal other GHRS/GTO programs, but no line_8: data have been obtained as of this writing. ! question: 10 section: 1 line_1: The PI and graduate students at CUA are actively working with line_2: members of the GHRS/IDT at NASA?GSFC with access to NASA line_3: computing facilities. The PI with graduate students have line_4: developed necessary theoretical models for proposed work. line_5: CUA also has ample coputing facilities (a cluster of VAX line_6: computers) and some of the same software as is available line_7: at NASA. ! !end of general form text general_form_address: lname: BRUHWEILER fname: FREDERICK title: DR. category: PI inst: CUA addr_1: 620 N.
