The calibration will be accomplished using objective line_7: prism observations of spectrophotometric standard stars. ! ! 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: Important characteristics of the objective prisms are the dimensions and line_2: displacements of the dispersed images on the FOC detectors. The following line_3: table lists the anticipated lengths and average offsets: line_5: length mean offset line_6: FUV/96 lambda 1200-lambda 6000 3.9 arcsec 7.6 arcsec line_7: NUV/96 lambda 1850-lambda 6000 9.7 arcsec 2.2 arcsec line_9: The objective prism modes of f/96 camera will be used in rather different line_10: fashion. In f/96 the prisms will primarily be used as low-dispersion line_11: spectrographs. Hence for each of these modes we intend to define a "standard" line_12: wavelength and photometrically calibrated position in the central 512x512 line_13: format using the mean offsets listed above. A suitable target for wavelength line_14: calibration is the star HZ 4. An exposure of this object in each line_15: of the "standard" positions should suffice. These line_16: exposures will also provide information on the filter red-leaks. ! !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: HZ4 name_2: GSC659-27 descr_1: A; 120; J; 702 pos_1: RA=03H 55M 21.7S +/- 0.1S, pos_2: DEC=+9D 47' 18.7" +/- 1", pos_3: PLATE-ID=02HA equinox: 2000 pm_or_par: N plate_req: N fluxnum_1: 2 fluxval_1: V=14.47, TYPE=DA4 ! targnum: 2 name_1: SAND-3 descr_1: A; 102; J; 703 pos_1: RA=16H 06M 28.328S +/- 1", pos_2: DEC=-35D 45' 13.59" +/- 1" equinox: 2000 fluxnum_1: 1 fluxval_1: B=14 ! ! end of fixed targets !
