It uses a UV line_3: standard star, BD+28d4211, to obtain medium resolution spectra line_4: through the G160M, G200M and G270M gratings. line_6: These data are to be obtained after the servicing mission is complete line_7: and before COSTAR optical bench deployment. line_9: These observations have been specified as Cycle 3 to ensure that the pre-SM line_10: GHRS aperture names are used. ! ! end of abstract general_form_proposers: lname: GILLILAND fname: RONALD title: DR. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: These data are obtained to provide a baseline of GHRS line_2: sensitivity post-servicing but pre-COSTAR deployment. ! question: 3 section: 1 line_1: Lines 100-113 obtain GHRS LSA and SSA spectra using the preferred standard star line_2: BD+28D4211. In the event that BD+28 is not available (in SAZ from late January line_3: through March), lines 400-413 obtain the same data using another standard star line_4: BD+75D325. These lines should only be used if BD+28 cannot be observed. ! question: 5 section: 1 line_1: PREREQUISITES: line_3: Baseline focal plane alignment (prop 4728) must be completed prior to execution. line_5: THESE DATA MUST BE OBTAINED PRIOR TO COSTAR DEPLOYMENT BUT AFTER HST SERVICING. line_7: THESE DATA MUST ALSO BE OBTAINED AT THE NOMINAL PRE-SM SECONDARY MIRROR line_8: SETTING. ! question: 5 section: 2 line_1: Exposure times are based on observed count rates. line_2: The goal is to obtain between 1000 - 10000 cts/diode in line_3: each substep bin. High S/N is required to identify small line_4: changes in sensitivity. Bright stars are used to keep the line_5: total test time as short as possible. The same star is line_6: used for all gratings to allow easy intercomparison and line_7: cross calibration. ! !end of general form text general_form_address: lname: GILLILAND fname: RONALD title: DR. category: PI inst: SPACE TELESCOPE SCIENCE INSTITIUE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: BD28D4211 name_2: GSC2214-1198 descr_1: J,702 pos_1: RA = 21H 51M 11.07S +/- 0.1S, pos_2: DEC = +28D 51' 51.8" +/- 0.5", pos_3: PLATE-ID=01LR equinox: 2000 pm_or_par: NO fluxnum_1: 1 fluxval_1: V=10.53 fluxnum_2: 2 fluxval_2: B-V=-0.34 ! targnum: 2 name_1: BD75D325 name_2: GSC4380-2196 descr_1: J,702 pos_1: RA = 08H 10M 49.31S +/- 0.1S, pos_2: DEC = +74D 57' 57.5" +/- 0.5", pos_3: PLATE-ID=00LQ equinox: 2000 pm_or_par: NO fluxnum_1: 1 fluxval_1: V=9.54 fluxnum_2: 2 fluxval_2: B-V=-0.37 ! ! end of fixed targets !
