To this end we line_4: propose an Astrometry Focus Test, line_5: This test line_6: should be run four times (at both ends and two locations in line_7: close proximity to the most probable 'best' focus) during line_8: the upcoming mini-sweep. That focus which produces the line_9: best results from our tests will be deemed the desirable line_10: astrometric focus. line_11: The mini-sweep focus test will be run at positions line_12: -50 -30 -10 0 +10 +30 +50 microns line_13: which will be denoted as runs 1, 2, 3, ...7. line_14: This proposal should be executed at runs 1, 3, 5, and 7 line_15: for a total of four times. ! ! 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: 3 section: 1 line_1: A) Acquire Guide Stars in FGS 1 and 3. line_2: 1) Perform position mode acquisitions line_3: a) Obtain and measure an 9th magnitude star in FGS2 line_4: b) Obtain and measure a 13th magnitude star in FGS2 line_5: c) Obtain and measure a 15 th magnitude star with line_6: two integration times (1.6s and 0.8s), in FGS2 line_7: d) Measure scale star for FGS#2 only line_8: 2) VERIFY TRANSFER FUNCTION SCAN line_9: a) Drive FGS 2 to expected location of test line_10: star of mag 12. line_11: b) Repeat for mag 14.5 star. line_12: These are multiple scans, 5 passes. line_13: B) Repeat A, with 2/3 aperture.
