This series of exposures will be obtained as close in time line_5: as possible. line_7: This test is composed of three parts: line_8: Part 1 - Linearity Test- Obtain a bias frame followed by images with line_9: F606W at increasing exposure times (from 12s to 200s for WFC and from line_10: 60s - 10s for PC on diffuse object and point source. line_11: Part 2 - QEH Test - Take 2 images with F439W then wait 20 minutes and line_12: take 2 more images. ! question: 4 section: 1 line_1: Instrument calibration. ! question: 5 section: 1 line_1: Prerequisites: 1) TECs on and Focus/Alignment activities complete through line_2: the AFM alignment stage. Fine Alignment and Focus need not be complete. ! !end of general form text general_form_address: lname: TRAUGER fname: JOHN category: PI inst: JPL addr_1: 4800 OAK GROVE BLVD. addr_2: MS179-225 city: PASADENA state: CA zip: 91109 country: USA phone: 818-354-9594 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: M-42 name_2: ORION NEBULA descr_1: J,705 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: J,705 pos_1: RA = 05H 32M 43.47S +/- 0.2S, pos_2: DEC = -05D 24' 15.01" +/- 1.33" equinox: 1950 ! ! end of fixed targets !
