We have demonstrated with line_3: previous GHRS data that S/N > 400 can be achieved, allowing line_4: lines with equivalent widths less than 1 milli-Angstrom to line_5: be detected and measured. This proposal builds on those line_6: results to search for lines of heavy elements lead, line_7: cadmium, and molybdenum. line_9: submitted May 17, 1993 for cycle 4 phase 2 ! ! end of abstract general_form_proposers: lname: EBBETS fname: DENNIS mi: C. inst: BALL AEROSPACE CORPORATION country: USA ! lname: CARDELLI fname: JASON mi: A. inst: UNIVERSITY OF WISCONSIN country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The structure of these observations is quite simple, and is line_2: based on proven successful strategies. Lines 10-30 define a line_3: target search with an RTB LSA exposure, followed by an LSA line_4: peakup, and finally an SSA RTB peakup. No image mode maps are line_5: required. Lines 100-130 define three grating setups, all line_6: using medium resolution modes, a substep pattern with four line_7: samples per diode width, four point comb addition, and line_8: standard four position fp-split. The exposure times will line_9: allow a total of 250000 counts per diode in each spectral bin line_10: when all subexposures are combined. The use of 8 subexposures line_11: ensures that no overflows will occur. ! question: 5 section: 1 line_1: There are no special requirements. There are no timing, line_2: orientation, interactions or special calibration requests. ! ! question: 9 section: 1 line_1: We used Zeta Oph as a standard star during SV to calibrate line_2: scattered light, detector granularity and linearity. We used line_3: these data to estimate cycle 4 count rates, and to specify line_4: the exposure times. ! question: 10 section: 1 line_1: Computing facilities, software & programming support. research assistants, line_2: manuscript preparation, publication support, travel expenses. ! !end of general form text general_form_address: lname: CARDELLI fname: JASON mi: A. inst: UNIV.
