For a given secondary mirror line_5: position, this test includes transfer scans at 5 line_6: positions within each FGS. Data from this test line_11: will provide important insight to the question line_12: concerning the FGSs' ability to acquire and track line_13: stars for both spacecraft guidance and astrometry line_14: science. ! question: 2 section: 2 line_1: This test will determine the line_2: characteristics of the s-curves as a function line_3: of the location in the line_4: focal plane and the position of the secondary mirror. ! question: 3 section: 1 line_1: O) Move secondary mirror to test position. line_2: A) Acquire brightest available Guide Stars in FGS 1 and 2 line_3: in Fine Lock if magnitude is < 13 otherwise use Coarse Track line_4: 1) Perform 5 transfer scans in FGS3 with the clear line_5: aperture at one of the central positions. line_6: 2) Repeat 1 with the 2/3 aperture. line_7: 3) Repeat 1 and 2 for FOUR other central line_8: positions, for a total of 5 positions and line_9: 50 scans. line_10: B) Repeat A with FGS2 as astrometer. line_11: C) Repeat A with FGS1 as astrometer. line_12: D) Obtain FOC image line_13: E) Return Secondary Mirror line_14: to starting position of test. ! 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 minimun jitter line_4: when data are analyzed. line_5: 32 Kbit data are required. ! question: 7 section: 1 line_1: Data reduction will be performed in the PASS, and line_2: data analysis will be carried out with the use line_3: of algorithms and software developed by HUGHES DOS. ! question: 10 section: 1 line_1: Computer facilities at HUGHES DOS home facility. ! !end of general form text general_form_address: lname: BRADY fname: WILLIAM mi: L. category: PI inst: HUGHES DOS ! lname: BASEDOW fname: ROBERT category: CON country: USA phone: 203-797-5838 ! ! 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 ! targnum: 2 name_1: GRW5824 descr_1: GRW+70D 5824 - SPECTROPHOTOMETRIC STANDARD descr_2: FOC STAR pos_1: RA=13H 38M 51.77S +/- 1S, pos_2: DEC=+70D 17' 8.5" +/- 0.5" equinox: 2000 comment_1: THIS STAR IS FOR FOC DIAGNOSTIC fluxnum_1: 1 fluxval_1: V=12.8 +/- 2 ! ! end of fixed targets !
