This will line_9: allow for refinement of the dispersion curve which was line_10: effectively determined from one source. This level of line_11: calibration would then allow for reduction of objective line_12: prism observations and subsequent scientific comparison of line_13: FOC results with ground-based and IUE spectra which should line_14: which should be free of systematic errors. ! ! 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 prisms will be used as low dispersion spectrographs line_10: to provide spectra of a symbiotic wavelength standard and line_11: a similar symbiotic star to act as a comparison. line_13: The orientation of the comparison star will reduce the line_14: confusion from nearby nebulosity and allow for clear extraction line_15: of the source spectra. The observations will also use the line_16: 256X1024 format so that the NUVOP spectra are not cut off at line_17: either the UV or red end. Thus, the stars must be well centered line_18: in the X-direction. The direct images will be offset by the same line_19: amount as the prism images so that the star's absolute position line_20: can be precisely known allowing for accurate zero-point for the line_21: the wavelength calculations of the spectra. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE ! lname: PARESCE fname: F. title: DR. category: PI inst: SPACE TELESCOPE SCIENCE INSTITUTE addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 301-338-4823 telex: 684-9101-STSCI ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: RX-PUP descr_1: A,155,J,703 pos_1: RA=08H 14M 12.4S +/- 0.1S, pos_2: DEC=-41D 42' 28" +/- 1" equinox: 2000 fluxnum_1: 1 fluxval_1: V=11.5 ! targnum: 2 name_1: HM-SGE descr_1: A,155,J,703 pos_1: RA = 19H 39M 41.4S +/-0.1S, pos_2: DEC = 16D 37' 33.0" +/-1" equinox: 1950 pm_or_par: NO fluxnum_1: 1 fluxval_1: V=11+/-1 ! ! end of fixed targets !
