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: KEYES fname: CHARLES (TONY) inst: STSCI country: USA ! lname: KINNEY fname: ANNE title: PI inst: STSCI country: USA ! lname: KORATKAR fname: ANURADHA inst: STSCI country: USA ! lname: TAYLOR fname: CINDY 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 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 STSCI. 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 line_7: subsequent science data. ! !end of general form text general_form_address: lname: KINNEY fname: ANNE category: PI inst: STSCI ! ! end of general_form_address records !
