One of the problems with line_6: interpretation of the temperature profiles obtained from ground-based line_7: occultation observations has been that the numerical inversion of the data is line_8: highly sensitive to photometric errors--especially in obtaining the mean line_9: temperature of the atmosphere. The much greater stability of photometry that is line_10: possible with the ST will allow us to obtain more accurate temperature profiles line_11: and permit a comparison of the atmospheric structures of the Jovian planets line_12: with much greater precision than has been possible in the past. We propose a line_13: series of three occultation observations for each Jovian planet and a series of line_14: three observations for Mars, which we shall use to further test the predictions line_15: of the tidal model. line_16: Revision History: Received on RPS 9/1/89; Added to SCCS 9/5/89 line_17: Updated for cycle 1 -- amanda bosh (MIT) 28 Sept 89 line_18: Changed 3 sequences from cycle1 to cycle2 - SALM 2/12/90 line_19: asb @ MIT 20 March 1990: changed cycle1 targs to real events; Changed line_20: scans, GUID TOL-asb@MIT 23June90; SEQ,SEQ NO GAP fixed--BJW 6/29/90,7/10/90. ! ! end of abstract general_form_proposers: lname: ROBINSON fname: EDWARD mi: L. inst: TEXAS, UNIVERSITY OF country: USA ! lname: BLESS fname: ROBERT mi: C. inst: WISCONSIN, UNIVERSITY OF country: USA ! lname: VAN CITTERS fname: G. mi: W. inst: NATIONAL SCIENCE FOUNDATION country: USA ! lname: DOLAN fname: JOSEPH mi: F. inst: NASA, GODDARD SPACE FLIGHT CENTER country: USA ! lname: WHITE fname: RICHARD mi: L. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: ELLIOT fname: JAMES mi: L. inst: MASSACHUSETTS INSTITUTE OF TECHNOLOGY country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: We plan to identify those occultations of sufficient signal-to-noise ratio to line_2: achieve the goals outlined in Section 2. Each observation proceeds as follows: line_3: 1) Obtain a WFPC image to determine the exact occultation parameters. line_4: 2) Monitor dark current on PMT for 5 minutes. line_5: 3) Acquire occultation candidate using onboard acquisition mode. line_6: 4) Scan along the track that the star will follow relative to the planet line_7: (along the planetary limb) in order to determine the planetary contribution line_8: to the background. line_9: 5) Start a continuous series of 10ms integrations enought before the predicted line_10: immersion time that scattered light will not affect the acquisition. The line_11: occultation observation will require simple tracking on the star before line_12: atmosphere immersion, complex tracking on the stellar image as it moves along line_13: the planetary limb, and simple tracking after atmosphere emersion. This line_14: sequence of integrations must be continuous. line_15: 6) Scan along the track that the star will follow relative to the planet. line_16: 7) Monitor dark current on PMT for 5 minutes. line_17: For some occultations to be observed in the far UV, prior multi-filter line_18: photometry of the object will be necessary in order to determine the most line_19: appropriate filter to use for the occultation. For now, we shall assume line_20: that the calibration and observation time will average about 45 minutes line_21: per occultation observed. The first three occultations will be observed with line_22: simple tracking because complex atmospheric tracking will not be line_23: available. All cycles. ! question: 4 section: 1 line_1: We can achieve a much better signal-to-noise ratio for the temperature profiles line_2: than has been possible from the ground for the following reasons: (i) the line_3: greatly improved photometric stability of ST photometry, which will line_4: substantially reduce the errors in the numerical inversion of the data that is line_5: necessary to obtain the temperature profiles; (ii) our ability to reject line_6: background light from the planetary limb by employing small focal plane line_7: apertures; and (iii) the absence of scintillation noise, which has strong line_8: components at frequencies comparable to the occultation timescale. ! question: 5 section: 1 line_1: Tracking the occulted star in some cases will require a real line_2: time update, due to its complicated path caused by refraction line_3: in the occulting planet's atmosphere and the uncertainties in line_4: predicting the ST orbit. ! question: 6 section: 1 line_1: A prior scan over 10 arc-seconds is needed to map the scattered light field, line_2: which is needed for the data reduction. ! question: 7 section: 1 line_1: Data will be reduced and analyzed at MIT with the VAX 11-750 belonging to the line_2: planetary astronomy group. ! question: 10 section: 1 line_1: Data reduction and analysis will be supported on computer facilities line_2: at MIT. ! question: 13 section: 1 line_1: Observations of the upper atmospheres of Mars and the Jovian planets with HSP line_2: through stellar occultations will provide infromation about the radiative and line_3: dynamical processes in this region. The temperature profiles obtained line_4: will allow testing of the various transfer models for each planet. ! !end of general form text general_form_address: lname: BLESS fname: ROBERT mi: C. category: PI inst: WISCONSIN, UNIVERSITY OF !
