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: HARMS fname: RICHARD inst: ARC country: USA ! 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 ! ! 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: Mode I real-time data will be used to monitor the start of the stellar line_2: observations. line_4: The FGS encoder values are to be extracted and recorded during the step and line_5: dwell sequences. line_7: OV/SV Prerequisites: line_8: Proposal 1443 at least 7 days prior to this test. line_9: The observations in this proposal (1528) need to be completed line_10: at least 7 days prior to the secnd visit in proposal 2195. line_12: Minimum/Delta plan objects: line_13: All observations are SV minimum plan. line_15: The dwell times on the Spatial Scan Form are determined as line_16: follows: line_17: ...SI Overhead: Dump UDL log 30s line_18: ..................BEG/END ACQ 15s line_19: ...Exposure time: 20s (R), 45s (B) line_20: ...Slew time: 10s line_22: The center point in the spatial scan should have the object line_23: centered in the aperture. ! question: 5 section: 2 line_1: Pointing stability of 10% of the smallest aperture used line_2: (4.3") - 0.43" - is 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: HARMS fname: RICHARD category: PI inst: APPLIED RESEARCH CORP addr_1: 8201 CORPORATE DRIVE addr_2: SUITE 920 city: LANDOVER state: MD zip: 20785 country: USA phone: 301-459-8442 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC-188-031 name_2: GSC4619-27 descr_1: STAR IN NGC 188 pos_1: RA= 00H 40M 03.20S +/- 0.01S, pos_2: DEC= 84D 55' 25.61" +/- 0.02" equinox: 1950 pm_or_par: Y pos_epoch_yr: 1950.00 ra_pm_val: -0.000247 ra_pm_unct: 0.000027 dec_pm_val: -0.0088 dec_pm_unct: 0.0005 comment_1: THE GSSS NAME IS GIVEN. fluxnum_1: 1 fluxval_1: V=15.08 fluxnum_2: 2 fluxval_2: B=15.72 ! ! end of fixed targets !
