They will use only the line_4: violet filter F336W. This proposal was submitted in February line_5: 1994 as a modified version of proposal 5173. This version line_6: removed several exposures which were found to be in conflict line_7: with those of the WFPC IDT. ! end of abstract general_form_proposers: lname: EBBETS fname: DENNIS inst: BALL AEROSPACE CORPORATION country: USA ! lname: MALUMUTH fname: ELIOT inst: COMPUTER SCIENCES CORPORATION country: USA ! lname: WALBORN fname: NOLAN inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: DAVIDSON fname: KRIS inst: UNIV OF MINNESOTA country: USA ! lname: WHITE fname: RICK inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: There are a total of six exposures specified; two each at line_2: three slightly different pointing positions. All use filter line_3: F336W. Lines 100 and 110 place the star at the geometric line_4: center of PC1, using the syntax PC1-FIX. A short 2 sec line_5: exposure will record the bright central object, and a longer line_6: 40 sec exposure will bring out the fainter surrounding line_7: nebulosity. This pair of exposures will be repeated with the line_8: star displaced by approximately 10 pixels in each direction line_9: on lines 200-210, and by 20 pixels in each direction on lines line_10: 300-310. ! question: 4 section: 1 line_1: Spatial resolution needed to study small line_2: scale structures in Homunculus, and to measure displacements line_3: and proper motions of outwardly moving ejecta. ! question: 5 section: 1 line_1: There are no real-time or special scheduling requirements. line_2: The entire Homunculus will fit onto the PC1 detector without line_3: any special orientation. ! ! question: 9 section: 1 line_1: An early set of WFC and PC images were obtained in cycle 0 line_2: as part of GTO proposal 1186. Our preliminary analyses were line_3: described in the proceedings of the STScI workshop on mass loss, line_4: and in a poster paper at the Atlanta AAS meeting in January, line_5: 1992. Further results on the motions of the North Condensation line_6: were presented at the Madison ASP conference in June, 1992, line_7: and at the HST workshop in Sardinia in July, 1992. ! question: 10 section: 1 line_1: Travel support, computer facilities, publication expenses ! !end of general form text general_form_address: lname: EBBETS fname: DENNIS title: DR. category: PI inst: BALL AEROSPACE SYSTEMS GROUP addr_1: HRS PROJECT AR-1 addr_2: P.O.
