A planetary satellite, Europa, is acquired into the GHRS 2.0 line_6: aperture using a WFC assisted proceudre. line_7: 2. A feature in the atmosphere of Jupiter is acquired into the line_8: GHRS 2.0 aperture using a WFC assisted procedure. line_9: 3. An enhanced GHRS flight software Target Acquisition X balance line_10: algorithm is tested. line_12: Revised 11/3/89 by PStanley to change target on exposure logsheet from line_13: Jupiter and its satellites and feature to Saturn. Jupiter is not line_14: available during July 1990 for GST8a run. line_16: Revised 2/6/90 by PStanley to change target back to Jupiter for SV. ! ! end of abstract general_form_proposers: lname: TRAFTON fname: LARRY inst: UNIV.

A planetary satellite, Europa, is acquired into the GHRS 2.0 line_6: aperture using a WFC assisted proceudre. line_7: 2. A feature in the atmosphere of Jupiter is acquired into the line_8: GHRS 2.0 aperture using a WFC assisted procedure. line_9: 3. An enhanced GHRS flight software Target Acquisition X balance line_10: algorithm is tested. ! question: 3 section: 1 line_1: Part 1 EL lines 3-5 line_2: WFC image of Jupiter system. Use OSS ellipse fitting s/w to line_3: center of planet. Calculate maneuver to translate Europa to line_4: GHRS 2.0 aperture. Perform GHRS on-board acquisition to improve line_5: centering. Take a short spectrum. line_7: Part 2 EL lines 8-12 line_8: WFC images in "V" and "UV" light. Identify atmospheric feature line_9: in OSS, calculate and execute maneuver to translate to GHRS 2.0 line_10: aperture. Feature may be better visible in difference or ratio line_11: of images than in either image separately. line_13: Part 3 EL lines 13-19 line_14: On-board GHRS acquisition of Io using enhanced X balance software. line_15: Io selected because it may have a non-uniform UV brightness line_16: distribution, and will be a good test of the new algorithm. ! question: 5 section: 1 line_1: Real time obs request: line_2: The primary purpose is to verify Mode I acquisition capability, which is by line_3: definition real-time. line_5: SV Prerequisites: HRS-07 WF/PC Assisted Target Acquisition line_6: (Proposal #1400) line_7: HRS-03 Camera Mode Sensitivity line_8: (Proposal #1349) line_10: SV Minimum Plan: EL lines 3-5, 8-12 line_11: SV Delta Plan: EL lines 13-19 line_12: Guiding tolerance: track motion of Jupiter to 0.25 arc seconds ! question: 5 section: 2 line_1: This proposal is being submitted for the first time in November 1985. It was line_2: not submitted with the June 1985 delivery because of our understanding that line_3: there would be an Observatory Level Test which would verify essentially the line_4: same requirements. During reviews of the OV-SV program over the past several line_5: months it became clear that the OLT did not satisfy all of the HRS concerns. line_6: We are therefore submitting this test as an HRS SV observation, to be run in line_7: addition to the "Acquisition and Tracking of Satellites" test submitted by line_8: John Caldwell. line_10: This test is similar enough to Caldwell's Acquisition and Tracking of line_11: Satellites test that the two may be scheduled together. This is not a line_12: requirement of either test, but may make more efficient use of HST observing line_13: time. line_14: Exposure logsheets were revised in September 1987 to include line_15: the offset from one satellite to another test. line_17: Test revised April 1989 during SV Scrub, and after discussions line_18: with Hal Weaver concerning likely OSS capabilities. ! question: 7 section: 1 line_1: Data reduction plans: line_2: The HRS data will consist of a focus diode field map image of the Large Science line_3: Aperture. Analysis will be simply displaying the image and verifying that the line_4: target is well centered. If the target is not well centered the test cannot be line_5: considered a success, and the reason for the error must be determined. This line_6: may require repeating the observation after correction of the fault. ! !end of general form text general_form_address: lname: EBBETS fname: DENNIS mi: C. category: PI inst: BALL AEROSPACE SYSTEMS GROUP addr_1: P.O.
