Short term stability of deflection calibration. line_4: 2. Spiral search sequence. line_5: 3. Production and processing of focus diode field maps. line_6: 4. Comparison of flux measurements to prescribed limits. line_7: 5. Use of wait after feature of the flight software. line_8: 6. Use of the GCOST feature of the flight software. line_9: 7. Recovery from a failed search. ! question: 3 section: 1 line_1: A short WFC image is taken for use in field identification. line_2: The target will be placed in the HRS Large Science Aperture using an line_3: interactive acquisition. Next, a focus diode field map will be made of the line_4: target to determine its flux. The telescope will then be pointed to line_5: deliberately place the star 2.5" outside the LSA. The flight software will line_6: be configured for the Target Search phase of target acquisition. It will line_7: execute a spiral search, map only. The telescope will be returned line_8: to the pointing with the target 2.5" from the LSA, and a spiral search without line_9: maps will be performed with incorrect flux limits to cause the search to fail. line_10: The pointing will again be returned to the spiral starting point, and a GCOST line_11: will be uplinked to perform a spiral search with maps using the correct flux. line_12: This test will exercise all target acquisition processes used through the line_13: completion of the Target Search phase. ! question: 5 section: 1 line_1: The Ground Control Observation Sequence Table (GCOST) is the basic way to line_2: communicate with the HRS for real-time observations. This test will verify line_3: GCOST use under real observing conditions. line_5: Prerequisites: line_6: 1. Proposal 1348 Relative Aperture Locations. line_7: 2. Proposal 1397 HRS/FGS Fine Alignment. line_8: 3. Proposal 1350 HRS Mode II TA Spiral Search Test. ! question: 7 section: 1 line_1: Only target acquisition data will be processed in real-time in the OSS. line_2: Flux limits for the GCOST will be determined from field maps in real-time. line_3: The maps and telescope pointing data will be correlated to evaluate the line_4: success of the test. ! question: 10 section: 1 line_1: 1. Test design support line_2: 2. Test execution support team line_3: 3. Data analysis facilities line_4: 4.
