The test will first image a star of a close (separation line_4: 15") double in the large aperture, and then allow the binary line_5: search onboard software to determine the centering for that line_6: object. A blind offset will then be performed to the second line_7: star of the pair, and a camera image obtained to verify the line_8: centering. The test will be repeated once to test for line_9: repeatability. line_11: This program (along with the other target acquisition tests) line_12: is the highest priority SV activity to be performed. ! ! end of abstract general_form_proposers: lname: ANGEL fname: ROGER inst: UNIVERSITY OF ARIZONA country: USA ! lname: MARGON fname: BRUCE inst: UNIVERSITY OF WASHINGTON country: USA ! lname: BARTKO fname: FRANK inst: MARTIN MARIETTA CORPORATION country: USA ! lname: DAVIDSEN fname: ARTHUR inst: JOHNS HOPKINS UNIVERSITY country: USA ! lname: HARMS fname: RICHARD inst: APPLIED RESEARCH CORPORATION country: USA ! lname: BOHLIN fname: RALPH inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: BURBIDGE fname: E. mi: M. inst: UNIVERSITY OF CALIFORNIA, SAN DIEGO country: USA ! lname: BEAVER fname: EDWARD inst: UNIVERSITY OF CALIFORNIA, SAN DIEGO country: USA ! lname: FORD fname: HOLLAND title: DR. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 0 line_1: Target acquisition is THE most important task to be verified line_2: in SV. The blind offset technique will probably not be line_3: used very frequently, but still needs to be tested. This test is to be line_4: performed one time here and once via prop 1428. This repetition will allow us line_5: to estimate the centering errors for this mode, which will, in turn, give us line_6: information on the accuracy of FOS photometry, as well as the accuracy for line_7: radial velocity measurements. ! question: 3 section: 0 line_1: In this test, we will observe one (1) close pair of stars to line_2: verify the functionality of the binary search target line_3: acquisition software of the FOS, as well as the blind offset line_4: capability. We will observe the object in the camera mode to line_5: check on its initial position, then let the software line_6: determine the centering of the object. We will then perform line_7: a blind offset to the second member of the pair, and take a line_8: camera image to check on its centering. line_10: CONTINUATION OF COMMENT FROM EXP. LOG. LINE 2: line_11: first SAM centers the offset star in the 4.3" aperture, and line_12: is FOS created. The second SAM is a blind pointing to the primary line_13: object, and is DF-224 controlled. The DF-224 also controls line_14: the move to the science aperture. ! question: 4 section: 0 line_1: Not applicable. ! question: 5 section: 0 line_1: line_5: SV prerequisites: line_6: Verification of mode II binary search target acquisition line_7: mode (Prop 2195). line_9: Minimum/Delta Plan objects: line_10: all observations are minimum plan line_12: This program may be done in PCS coarse track, if necessary. line_13: Pointing stability of 10% of the smallest aperture used line_14: (1.0") - 0.10" - is required. ! question: 6 section: 0 line_1: This test is not stray light sensitive. ! question: 7 section: 0 line_1: Data reduction will be performed at the ST ScI, and the analysis will be line_2: performed using FOS IDT computer facilities. Since this test is strictly a line_3: verification, no pipeline calibration data will be obtained. ! question: 10 section: 0 line_1: Data analysis, research assistant support, and funding will be provided line_2: under NASA's FOS GTO contract(s). ! !end of general form text general_form_address: lname: FORD fname: HOLLAND category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC-188-210 descr_1: STAR 210 IN NGC 188 pos_1: RA = 00H 36M 33.87S +/- 0.01S, pos_2: DEC = +85D 29' 03.5" +/- 0.3" equinox: 2000 pm_or_par: Y pos_epoch_bj: J pos_epoch_yr: 2000.00 ra_pm_val: -0.000693 ra_pm_unct: 0.000067 dec_pm_val: -0.0095 dec_pm_unct: 0.0013 fluxnum_1: 1 fluxval_1: V=12.72 +/- 0.05 ! targnum: 2 name_1: NGC-188-210A descr_1: COMPANION STAR OF descr_2: NGC 188, STAR 210 pos_1: RA-OFF = -9.352S +/- 0.1S, pos_2: DEC-OFF = -7.72" +/- 0.1", pos_3: FROM 1 fluxnum_1: 1 fluxval_1: V=13.38 +/- 0.5 ! ! end of fixed targets !
