In each case, a filter-pair is line_3: used to reduce the red leak. This observation will serve as a test to line_4: determine which filter-pair produces the optimum signal, by maximizing line_5: throughput at auroral wavelengths and minimizing both near (1800-2000) line_6: and long (visible) wavelength contamination. Continuum observations, also line_7: with two different filter-pairs, will improve the accuracy of line_8: position-finding on Jupiter through detailed limb-fitting. At auroral line_9: wavelengths, auroral emission dominates continuum emission, making limb- line_10: fitting impossible. ! ! end of abstract general_form_proposers: lname: CALDWELL fname: JOHN mi: J. inst: YORK UNIVERSITY country: CANADA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: S/N estimate based on previous HST images, with FOC pixel binning to 2x2 line_2: (arcsec)^2 assumed. ! question: 5 section: 1 line_1: The south-polar observations should be completed as soon after February line_2: 1, 1993 as possible, both to improve planning future HST observations and line_3: to minimize Jupiter's motion in the sky. The latter will facilitate keep- line_4: the entire set of observations on one guide-star pair, which is essential line_5: for subsequently determining accurate auroral positions on Jupiter. ! question: 7 section: 1 line_1: Images will be calibrated and binned as necessary to produce optimum line_2: information. Exposures are limited not only by photons but also by planetary line_3: rotation, so that standard S/N estimates are not meaningful. Previous line_4: experience with HST/FOC images of the Jovian aurora shows that the chosen line_5: exposure times will produce excellent images. ! question: 13 section: 1 line_1: Auroral imaging of the polar regions of Jupiter will be performed with the line_2: FOC, using either filters F140W and F152M or F175W and F152M in series, to line_3: reduce red leak and provide reasonable sensitivity to H2 emission at 1600 A. line_4: Continuum images at 1700A and at 2200A will also be obtained. ! !end of general form text general_form_address: lname: CALDWELL fname: JOHN mi: J. title: DR. category: PI inst: YORK UNIVERSITY addr_1: PHYSICS DEPT addr_2: 4700 KEELE ST. city: NORTH YORK state: ON zip: M3J 1P3 country: CANADA ! ! end of general_form_address records !
