Those observations did show that line_7: the FFT2 region was suitable for flat fielding purposes. This propsoal line_8: replaces the FFS1-3 exposures in the 1515 proposal with exposures using line_9: a different observation strategy (a number of fixed offsets rather than line_10: continuous scans). The data are required to update the FOC photometric line_11: files used in SOGS pipeline processing. ! ! end of abstract general_form_proposers: lname: PARESCE fname: FRANCESCO title: DR. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Before any meaningful imaging science can be accomplished, the line_2: FOC has to be flat fielded to at least 3% accuracy in order to line_3: remove the instrument signature. Since the pixel-to-pixel variations line_4: vary only slowly with wavelength, this calibration needs to be performed line_5: in small no. of UV filter wavelengths chosen to cover uniformly line_6: the UV response range of the FOC. The only inherently flat field line_7: for the FOC is the Lyman alpha geocoronal emission pattern and, line_8: possibly, certain regions of the Orion Nebula near the Trapezium line_9: (the inner nebula). This proposal will use the Orion Nebula line_10: to generate a flat field at one UV wavelength for F/96 and F/48. line_11: This will be accomplished by observing a relatively uniform region line_12: of the nebula with 10 overlapping exposures for F/96 and 11 overlapping line_13: exposures for F/48. Previous exposures of the region show that although line_14: it is smooth, it is not uniform. The overlapping exposures will be used line_15: to determine the variation in surface brightness of the nebula across line_16: the field of view and therefore allow the determination of the actual line_17: flat field response of the FOC. The total time for this proposal is line_18: 10.98 hours ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: FFT3 name_2: NGC1976 descr_1: ORION NEBULA pos_1: RA=5H 35M 21.2S +/- 0.1S, pos_2: DEC=-5D 21' 7.0" +/- 0.5" equinox: 2000 ! targnum: 2 name_1: FFT3-A name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 3 name_1: FFT3-B name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=15" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 4 name_1: FFT3-C name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=15" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 5 name_1: FFT3-D name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=-15" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 6 name_1: FFT3-E name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=-15" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 7 name_1: FFT3-F name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=5" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 8 name_1: FFT3-G name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=-5" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 9 name_1: FFT3-H name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=1.33" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 10 name_1: FFT3-I name_2: NGC1976 descr_1: ORION NEBULA pos_1: XI-OFF=-1.33" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 11 name_1: FFT3-J name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=5" +/- 0.1", pos_2: ETA-OFF=-10" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 12 name_1: FFT3-K name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=-10" +/- 0.1", pos_3: FROM 1 equinox: 2000 ! targnum: 13 name_1: FFT4 name_2: NGC1976 descr_1: ORION NEBULA pos_1: RA=5H 35M 21.2S +/- 0.1S, pos_2: DEC=-5D 21' 7.0" +/- 0.5" equinox: 2000 ! targnum: 14 name_1: FFT4-A name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 15 name_1: FFT4-B name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=6" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 16 name_1: FFT4-C name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=6" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 17 name_1: FFT4-D name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=-6" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 18 name_1: FFT4-E name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=-6" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 19 name_1: FFT4-F name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=2" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 20 name_1: FFT4-G name_2: NGC1976 descr_1: ORION NEBULA pos_1: XI-OFF=-2" +/- 0.1", pos_2: ETA-OFF=0" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 21 name_1: FFT4-H name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=-1" +/- 0.1", pos_2: ETA-OFF=1" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 22 name_1: FFT4-I name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=2" +/- 0.1", pos_2: ETA-OFF=-4" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! targnum: 23 name_1: FFT4-J name_2: NGC1976 descr_1: ^ pos_1: XI-OFF=0" +/- 0.1", pos_2: ETA-OFF=-4" +/- 0.1", pos_3: FROM 13 equinox: 2000 ! ! end of fixed targets !
