Images through the five most used emission line_5: line filters will be taken to verify ground based calibrations. line_6: This test must be done after TECs turned on. line_8: EXPOSURE LINES 7 AND 16 CHANGED FROM NON-INT TO NO GAP BECAUSE OF line_9: TRANS ERRORS. ! ! end of abstract general_form_proposers: lname: DANIELSON fname: G. mi: E. inst: CALTECH country: USA ! lname: WESTPHAL fname: JAMES mi: A. inst: CALTECH country: USA ! lname: GUNN fname: JAMES mi: E. inst: PRINCETON UNIVERSITY country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 0 line_1: These on-orbit tests are necessary to determine the line_2: linearity and noise response of the WF/PC detectors. Quantum line_3: efficiency hysteresis is also measured. line_4: Images of M-42 will be obtained through the set of the most line_5: commonly used narrow band filters. By comparing these line_6: images with ground-based spectrophotometry we will derive line_7: an absolute calibration for these filters which is line_8: independent of ST observations of standard stars, line_9: thereby providing a check on our ability to calibrate line_10: other narrow band filters using standard star data. line_11: Comparison with ground based imagery will provide line_12: a check on our narrow band flats. ! question: 3 section: 1 line_1: Filter F555W will be selected, and two bias frames taken. line_2: A sequence of 5 observations of one target follows, during line_3: which exposures are taken of increasing duration. line_4: This is followed by a QEH measurement line_5: consisting of three rapid exposures using F439W, a wait of line_6: 20 minutes, and two subsequent rapid exposures. The test line_7: is performed for both the WFC and the PC; however, the line_8: exposures for the PC sequence are approximately five times line_9: the duration of those for the WFC sequence. A series of exposures using line_10: narrow emission line filters is done on this same target to line_11: derive accurate emission line intensity calibrations in the WFC. line_12: TECs must be on and the CCDs as cold as -80. ! question: 5 section: 1 line_1: Real-time contact is not required for commanding and data reduction. ! question: 6 section: 1 line_1: ! question: 8 section: 1 line_1: ! !end of general form text general_form_address: lname: DANIELSON fname: G. mi: E. category: COI inst: CALTECH addr_1: DIVISION OF GEOLOGICAL & PLANETARY SCIENCES city: PASADENA state: CA zip: 91125 country: USA phone: (818) 356-6861 ! lname: WESTPHAL fname: JAMES mi: A. category: PI inst: CALTECH addr_1: DIVISION OF GEOLOGICAL & PLANETARY SCIENCE city: PASADENA state: CA zip: 91125 country: USA phone: (818) 356-4900 ! lname: GUNN fname: JAMES mi: E. category: DEP inst: PRINCETON UNIVERSITY addr_1: ASTROPHYSICAL SCIENCE addr_2: PEYTON HALL city: PRINCETON state: NJ zip: 08540 country: USA phone: (609) 452-3802 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: M-42-WF name_2: ORION NEBULA descr_1: DIFFUSE OBJECT pos_1: RA=05H 32M 43.5S +/- 0.1S, pos_2: DEC=-05D 23' 13" +/- 1" equinox: 1950 ! targnum: 2 name_1: M-42-PC name_2: ORION NEBULA descr_1: DIFFUSE OBJECT pos_1: RA=05H 32M 51.2S +/- 0.1S, pos_2: DEC=-05D 26' 13" +/- 1" equinox: 1950 ! ! end of fixed targets !
