Lupie, R. Bohlin, and A. Holm. line_7: This program has the highest priority. Phases I to III must be completed line_8: before attempting observations of any other stellar targets. ! ! 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: BOHLIN fname: RALPH inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: FORD fname: HOLLAND inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: BEAVER fname: EDWARD inst: UNIVERSITY OF CALIFORNIA, SAN DIEGO country: USA ! lname: BURBIDGE fname: MARGARET inst: UNIVERSITY OF CALIFORNIA, SAN DIEGO country: USA ! lname: KINNEY fname: ANNE mi: L inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: See Abstract. ! question: 3 section: 1 line_1: Since the FOS apertures are nested about the same position on the photocathode, line_2: an accurate plate scale and orientation cannot be derived as for the other line_3: instruments with widely separated apertures, as projected on the photocathodes. line_4: Therefore, the precise FOS place scale and orientation will be determined as line_5: follows: line_7: Perform a raster step and dwell sequence in the 4.3 arcsec aperture, using line_8: a 1 arcsec step size on a 4x4 arcsec grid. The edges of the 4.3 arcsec line_9: aperture should be avoided to prevent vignetting effects. An aperture line_10: map is required at each step in the dwell sequence. ! question: 5 section: 1 line_1: line_4: The FGS encoder values are to be extracted and recorded during the step and line_5: dwell sequences. line_11: The center point in the spatial scan should have the object line_12: centered in the aperture. ! question: 5 section: 2 line_1: Pointing stability of 50 mas (coarse track) required. ! question: 7 section: 1 line_1: Data reduction will be performed at the ST ScI, using FOS IDT Computer line_2: hardware. The results of this aperture location calibration are relevant to line_3: the project data base, so that the priority is very high. Data from Phases I - line_4: III must be reduced before any other observations using stellar targets can be line_5: attempted. ! !end of general form text general_form_address: lname: KINNEY fname: ANNE mi: L category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: GRW+70D5824 name_2: GSC4405-1633 descr_1: DA3 PHOTOMETRIC STD pos_1: RA= 13H 38M 51.15S +/- 0.2S, pos_2: DEC= 70D 17' 08.6" +/- 1.0", pos_3: PLATE-ID=0001 equinox: 2000 pm_or_par: N comment_1: TARGET COORDS HAVE BEEN CORRECTED comment_2: PROPER MOTION ASSUMING OBS EPOCH comment_3: OF 1991.6 fluxnum_1: 1 fluxval_1: V=12.77 ! ! end of fixed targets !
