The technique used derives line_4: the relative LSF difference between the LSA and SSA by line_5: direct least-squares solution for the LSF relating spectra line_6: acquired through the two apertures. ! ! end of abstract general_form_proposers: lname: HULBERT fname: STEVE inst: ST SCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Knowledge of the line-spread-function (LSF) for large (LSA) line_2: aperture GHRS is essential for any quantitative analysis line_3: of spectra taken through the LSA. This is independent of any line_4: deconvolution issues. This test will provide LSF information line_5: for the ECH-A and G140L gratings. ! question: 5 section: 1 line_1: Exposure times are selected to yield S/N about 100 for LSA, line_2: and 70, or greater, for SSA. These are levels required for line_3: adequate extraction of the relative PSF relating the two line_4: apertures. ! question: 7 section: 1 line_1: line_4: Data will be analyzed at the ST ScI using fully developed and line_5: tested software. ! question: 13 section: 1 line_1: line_2: High signal-to-noise spectra will be obtained through both line_3: GHRS apertures at three basic wavelengths chosen to: line_4: 1) well span the full UV wavelength range accessible to line_5: the GHRS line_6: 2) provide scientifically valuable spectra. ! !end of general form text general_form_address: lname: HULBERT fname: STEPHEN mi: J. category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA phone: 301-338-4911 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: HD141556 name_2: CHI-LUP descr_1: J,704 pos_1: RA=15H 47M 46.468S +/- 0.2", pos_2: DEC=-33D 28' 35.36" +/- 0.2" equinox: 1950 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: -0.000600 ra_pm_unct: 0.000667 dec_pm_val: -0.0320 dec_pm_unct: 0.0100 rv_or_z: V=+5 comment_1: BP HG MN STAR fluxnum_1: 1 fluxval_1: V=3.95+/-.05, TYPE=BP fluxnum_2: 2 fluxval_2: F-CONT(1362)=1.8 E-10 fluxnum_3: 3 fluxval_3: F-CONT(1868)=1.9 E-10 fluxnum_4: 4 fluxval_4: F-CONT(2682)=1.0 E-10 ! ! end of fixed targets !
