These data will be used to line_4: determine the linearity and instrument readout noise level line_5: for each CCD. This series of exposures will be obtained as line_6: close in time as possible and should go to the tape recorder. line_8: Linearity Test- Obtain a bias frame followed by line_9: images with F606W at increasing exposure time (from 12s to line_10: 200s for WFC and from 60s - 10s for PC on diffuse object line_11: and point source. ! question: 4 section: 1 line_1: Instrument calibration. ! question: 5 section: 0 line_1: Schedule the set of 1000s and the 2000s PC exposures each line_2: in one orbit, using as much dark time as possible. Drop line_4: strict "DARK TIME" req't if needed. The sequence for the line_5: PC will take two orbits and the long exposure should be line_7: done in the second orbit. ! question: 7 section: 1 line_1: These data will be reduced and the numbers and plots line_2: included in a WF/PC instrument report. ! !end of general form text general_form_address: lname: MACKENTY fname: JOHN mi: W title: DR. category: PI inst: ST SCI ! lname: MACKENTY fname: JOHN mi: W. inst: STSCI country: USA phone: (301) 338-4559 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: M-42 name_2: ORION NEBULA descr_1: DIFFUSE OBJECT pos_1: RA = 05H 32M 44S +/- 0.2S, pos_2: DEC = -05D 24' 15" +/- 1.5" equinox: 1950 ! targnum: 2 name_1: M-42REF name_2: ORION NEBULA descr_1: DIFFUSE OBJECT pos_1: RA = 05H 32M 43.47S +/- 0.2S, pos_2: DEC = -05D 24' 15.01" +/- 1.33" equinox: 1950 ! ! end of fixed targets !
