Maps of the aperture image, with TALED line_3: illumination at approximately 3 minute intervals will be used to line_4: determine the amount of motion in both X and Y directions. Spectra line_5: obtained with the onboard calibration lamps in RAPID readout mode line_6: will permit determination of the uniformity of the image drift across line_7: the diode array and an accurate sensitivity and phase measurement. line_8: The latter data will also be used to determine how well the effect can line_9: be corrected and if second order effects (hysteresis, local field line_10: distortion due to permeable materials in the vicinity of the Digicons, line_11: influence of the S/C magnetic torquers) are substantial. ! ! end of abstract general_form_proposers: lname: BEAVER fname: EDWARD inst: UNIVERSITY OF CALIFORNIA, SAN DIEGO country: USA ! lname: BAITY fname: BILL inst: UNIVERSITY OF CALIFORNIA, SAN DIEGO country: USA ! lname: HARTIG fname: GEORGE title: PI inst: STSCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Aperture maps, with TALED illumination, will be obtained over a full orbit, line_2: at four different S/C pointings, at approximately 3 minute intervals, to line_3: determine amout of image drift due to the geomagnietic field in both X and Y line_4: Digicon coordinate. A similar set of internal cal lamp spectra, obtained at line_5: higher time resolution, will permit a more accurate characterization of the line_6: effect, over the full length of the diode array. ! question: 5 section: 1 line_1: All observations are internal and may be obtained under gyro control. ! question: 6 section: 1 line_1: This test is not stray light sensitive. All observations are internal line_2: cal lamp and TALED measurements. ! question: 7 section: 1 line_1: Data reduction will be performed at UCSD, and the analysis will be line_2: performed using FOS IDT computer facilities. line_4: This program will determine the parameters required to compute corrections line_5: in both the X and Y coordinates for the geomagnetically induced image line_6: drift. These corrections are required to properly reduce OV tests 2188, 2098, line_7: 2099, and 1441, SV tests 1309, 1528, 1429, and 1430, and subsequent science line_8: data, with software tools which the FOS IDT is currently developing. ! question: 10 section: 1 line_1: Data analysis, research assistant support, and funding will be provided line_2: under NASA's FOS GTO contract(s). ! !end of general form text general_form_address: lname: HARTIG fname: GEORGE category: PI inst: STSCI ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NORTH descr_1: NORTH CELESTIAL POLE pos_1: RA = 00H 00M 00.0S +/- 1H, pos_2: DEC = +90D 00' 00.0" +/- 1D, equinox: 2000 ! targnum: 2 name_1: SOUTH descr_1: SOUTH CELESTIAL POLE pos_1: RA = 00H 00M 00.0S +/- 1H, pos_2: DEC = -90D 00' 00.0" +/- 1D, equinox: 2000 ! targnum: 3 name_1: EQ6 descr_1: POINT NEAR CEL EQUATOR pos_1: RA = 06H 00M 00.0S +/- 1H, pos_2: DEC = +00D 00' 00.0" +/- 1D, equinox: 2000 ! targnum: 4 name_1: EQ12 descr_1: POINT NEAR CEL EQUATOR pos_1: RA = 12H 00M 00.0S +/- 1H, pos_2: DEC = +00D 00' 00.0" +/- 1D, equinox: 2000 ! ! end of fixed targets !
