To this end we line_4: propose an Astrometry Focus Monitor. line_5: This test line_6: can be run at any time during the year, between 15 August line_7: and 29 April. ! ! 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: line_2: A) Acquire Guide Stars in FGS 1 and 2. line_3: 1) Perform TRANSFER FUNCTION SCANS line_4: a) Locate and measure star 625 in FGS3 line_5: b) Locate and measure star 633 in FGS3 line_6: c) Locate and measure star 640 in FGS3 line_7: d) Locate and measure star 679 in FGS3 line_8: These are multiple scans, 5 passes with 2/3 aperture. line_11: This proposal should be executed whenever a focus line_12: check is required. There are roll constraints line_13: the first time the proposal is run. Once line_14: the Astrometry Team determines which two stars line_15: have the best characteristics for this test, the line_16: spcaecraft roll will be constrained to always put line_17: these two stars either in the same place in FGS #3 line_18: or in each other's place (swapped positions within line_19: FGS #3). The proposal is written assuming that stars line_20: 625 and 640 are the prime targets. The off-nominal line_21: roll angle may be changed if one or both stars are line_22: discovered to be unacceptable. ! question: 5 section: 1 line_1: Proposal may not be run between 29 April and 15 August. line_2: From 15 August until 22 December orient = . line_3: From 23 December until 29 April orient = . ! question: 7 section: 1 line_1: Data reduction and analysis will be carried out with the use line_2: of algorithms and line_3: software developed by STAT.
