Our 3x1 hour observations will yield results accurate to 2.5%, line_3: and 5 degrees in a resolution element of 0.06". This will complement longer line_4: wavelength studies that can be better made with the WFC. It enables us to line_5: begin a longer term investigation of the motions reported in the wisps. Since line_6: we shall see 3727 filaments in U we propose a 1 hour 3727 exposure to subtract line_7: off the line contribution. ! ! end of abstract general_form_proposers: lname: MCLEAN fname: IAN mi: S. inst: ROYAL OBSERVATORY, EDINBURGH country: UNITED KINGDOM esa: X ! lname: DISNEY fname: MICHAEL mi: J. inst: UNIVERSITY COLLEGE, CARDIFF country: UNITED KINGDOM esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Do exposures 1 to 3 in cycle 2 line_3: Remainder in cycles 3 to 5 line_5: It is important that all 7 exposures cover the same field. ! question: 12 section: 1 line_1: line_2: This is an FOC IDT program. The one we are using to check out our line_3: polarimetry capability. ! question: 13 section: 1 line_1: We are proposing U band polarmetry in the Crab Nebula near the pulsar with the line_2: FOC. In 4 hours at F/96 we expect to get polarization in a resolution element line_3: of 0.06" acurate to 2.5% and 5 degrees. Also starting study of Wisp movements. ! !end of general form text general_form_address: lname: DISNEY fname: MICHAEL mi: J. category: PI inst: UNIVERSITY COLLEGE addr_1: DEPARTMENT OF ASTRONOMY addr_2: P.O.
