This test is intended to be executed line_5: as often as possible, each time at a different secondary line_6: mirror position. Transfer scans will be observed at the line_7: center of each FGS, using both the full aperture line_8: F583W and the 2/3 PUPIL. Results from this test should line_9: greatly accelerate the location of the best secondary line_10: mirror position which optimizes S-curve modulation. ! ! end of abstract general_form_proposers: lname: JEFFERYS fname: WILLIAM mi: H. inst: TEXAS, UNIVERSITY OF country: USA ! lname: BENEDICT fname: GEORGE mi: F. inst: TEXAS, UNIVERSITY OF country: USA ! lname: DUNCOMBE fname: RAYNOR mi: L. inst: TEXAS, UNIVERSITY OF country: USA ! lname: FRANZ fname: OTTO mi: G. inst: LOWELL OBSERVATORY country: USA ! lname: FREDRICK fname: LAURENCE mi: W. inst: VIRGINIA, UNIVERSITY OF country: USA ! lname: HEMENWAY fname: PAUL mi: D. inst: TEXAS, UNIVERSITY OF country: USA ! lname: SHELUS fname: PETER mi: J. inst: TEXAS, UNIVERSITY OF country: USA ! lname: VAN ALTENA fname: WILLIAM mi: F. inst: YALE UNIVERSITY country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: OTA-FGS DIAGNOSTICS line_2: The Astrometry Science Team and HDOS need to assess line_3: the FGS transfer function as a function of secondary line_4: mirror position. This test is intended to be executed line_5: as often as possible, each time at a different secondary line_6: mirror (SM) position. Following a repositioning of the SM, line_7: transfer scans will be observed at the center of line_8: each FGS pickle, using both the full aperture F583W and the line_10: returned to its pre-test position. Results from this test line_11: should greatly accelerate the understanding of the the line_12: complex relationship between FGS and OTA contributions to line_13: the observed FGS performance, leading to an optimization line_14: for guidence and astrometry. ! question: 3 section: 1 line_1: line_2: A) Acquire brightest available Guide Stars in FGS 1 and 2 line_3: in fine lock if magnitude < 13th, otherwise coarse track. line_4: 1) Perform 1 transfer scans in FGS3 with the clear line_5: aperture at pickle center. line_6: 2) Repeat 1 with the 2/3 aperture. line_10: B) Repeat A with FGS2 as astrometer. line_11: C) Repeat A with FGS1 as astrometer. ! question: 5 section: 1 line_1: The bright target star is required to provide high signal to line_2: noise in the transfer scan data. The brightest available line_3: guide stars are desired to provide highest fidelity fine lock line_4: guidance for removal of vehicle jitter when data is analyzed. line_5: 32 Kbit data are required. If finelock guidence is not line_6: available, the observations should proceed using the ! question: 7 section: 1 line_1: Initial data reduction and analysis will be carried out line_2: with the use of algorithms and software developed by STAT. line_3: Such reductions and analyses will require the use of data line_4: processing facilities both at STScI and at the home line_5: institutions of STAT members. Further, more detailed data line_6: will be carried out by both HDOS and the STScI. ! question: 10 section: 1 line_1: Computer facilities at STAT members' institutions. ! !end of general form text general_form_address: lname: JEFFERYS fname: WILLIAM mi: H. category: PI inst: TEXAS, UNIVERSITY OF ! lname: BENEDICT fname: GEORGE mi: F. category: CON inst: UNIVERSITY OF TEXAS addr_1: ASTRONOMY DEPARTMENT city: AUSTIN state: TX zip: 78712 country: USA phone: 512-471-3448 telex: TEXASTRO ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: FGS.CHAR1 descr_1: FGS STAR descr_2: UPGREN69 pos_1: RA=9.46625D +/- .0004D, pos_2: DEC=84.9632778D +/- .002D equinox: 1950 comment_1: THIS STAR IS FOR TRANSFER SCANS fluxnum_1: 1 fluxval_1: V=9.58 +/- 0.05 ! ! end of fixed targets !
