Determine the coordinates of the LSA in V2/V3 coordinates line_3: with an accuracy of 0.02 arcsec. line_4: 2. Determine the coordinates of the SSA in V2/V3 coordinates line_5: with an accuracy of 0.02 arcsec. ! question: 3 section: 1 line_1: There are three parts to this test. In the first part the probe star is line_2: acquired and centered in the LSA using a Mode I target acquisition. It is line_3: scanned across one edge of the aperture in a series of fine step and dwell line_4: maneuvers executed by DF-244. A direct downlink HRS observation is started line_5: to continuously monitor the flux through the aperture with accurate time line_6: resolution. The flux will be correlated with the V2/V3 position of the image line_7: during data reduction. The HRS must be instructed to continue to take line_8: scientific data while the telescope is moving. The direct downlink observation line_9: must be terminated by setting HRS event flag 2. This procedure will be line_10: repeated for all four edges of the LSA. The second part of the test locates line_11: the SSA. A series of step and dwell maneuvers will move the probe star over a line_12: grid of closely spaced points centered on the expected position of the line_13: aperture. A direct downlink observations will be in progress monitoring the line_14: flux as a function of time. In the third part the probe star will be returned line_15: to the nominal center of the LSA and a single field map will be obtained. line_16: During the field map a WFC boresight exposure will be taken. line_17: These observations need only be made with one acquisiiton mirror and detector. line_19: This test requires maximum HRS positional accuracy. Therefore a 1 hour warm line_20: up on detector 2 is required before starting the test. ! question: 5 section: 1 line_1: Real time contact is required for Mode I target acquisition. line_3: Allow at least four days between HRS/FGS Coarse Alignment and this test during line_4: OV line_6: This test should be repeated every 28 days +/- 7 days during SV for a total of line_7: 5 times during SV. line_9: Prerequisites: line_10: 1.
