The objective of this program is to resolve the line_3: spatial structure perpendicular to the direction of motion of the shock front line_4: and the derive information on the changes in grain characteristics across the line_5: shock by observing the variation in intensity and wavelength dependence of line_6: scattered light. line_8: Our target is a section of the bright bar between THETA^2 Ori and the line_9: Trapezium which is easily seen in continuum scattering as well as in nebular line_10: emission lines. ! ! end of abstract general_form_proposers: lname: JAKOBSEN fname: PETER inst: ESA, ESTEC country: NETHERLANDS esa: X ! lname: CHLEWICKI fname: G. inst: LEIDEN, UNIVERSITY OF country: NETHERLANDS esa: X ! lname: GREENBERG fname: J. mi: M. inst: LEIDEN, UNIVERSITY OF country: NETHERLANDS esa: X ! lname: PARESCE fname: FRANCESCO inst: ESA, SPACE TELESCOPE SCIENCE INSTITUTE country: USA esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The whole of this program is to be executed in Cycle 2 or thereafter. ! question: 4 section: 1 line_1: Only the FOC can image at high enough spatial resolution in the near and line_2: far ultraviolet to resolve the internal structure of a molecular shock. ! question: 13 section: 1 line_1: line_2: A shock molecular region in the bar of the Orion Nebula will be imaged in the line_3: ultraviolet with the f/96 camera of the FOC. The objective is to resolve the line_4: spatial structure of the shock and derive information on changes in grain line_5: properties across the shock by observing the variation in the intensity and line_6: wavelength dependence of scattered light. ! !end of general form text general_form_address: lname: JAKOBSEN fname: PETER category: PI inst: ESTEC addr_1: SPACE SCIENCE DEPARTMENT addr_2: POSTBUS 299 addr_3: 2200 AG city: NOORDWIJK country: NETHERLANDS phone: 31 1719 83614 telex: 39098 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: ORION-A descr_1: FIELD IN ORION BAR pos_1: RA = 5H 33M 00.0S +/- 0.1S, pos_2: DEC = -5D 30' 00" +/- 1" equinox: 1950 pm_or_par: N acqpr_1: EXT plate_req: Y plate_avail: N fluxnum_1: 1 fluxval_1: SURF(B)=14 ! targnum: 2 name_1: ORION-B descr_1: ^ pos_1: RA = 5H 33M 00.0S+/- 0.1S, pos_2: DEC = -5D 30' 00" +/- 1" equinox: ^ pm_or_par: ^ acqpr_1: ^ plate_req: Y plate_avail: N fluxnum_1: 1 fluxval_1: ^ ! ! end of fixed targets !
