An emission-line star will be observed using the line_4: four main prisms to refine the wavelength calibration obtained for the line_5: F/96 prisms in SV, and to calibrate the F/48 prisms for the first time. line_6: The photometric calibration of the F/48 prisms will be accomplished using line_7: 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: 2 section: 1 line_1: Prerequisites: Optical Focus Test (FOC-03; 1507), line_2: Mode III target acquisition ! 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_8: FUV/48 lambda 1200-lambda 6000 3.9 arcsec 7.7 arcsec line_9: NUV/48 lambda 1850-lambda 6000 4.9 arcsec 1.3 arcsec line_11: The objective prism modes of the two cameras will be used in rather different line_12: fashion. In f/96 the prisms will primarily be used as low-dispersion line_13: spectrographs. Hence for each of these modes we intend to define a "standard" line_14: wavelength and photometrically calibrated position in the central 512x512 line_15: format using the mean offsets listed above. A suitable target for wavelength line_16: calibration is the star San. 3. An exposure of this object in each line_17: of the "standard" positions should suffice. For the f/48 photometric line_18: calibration we propose to observe the standards LB227 and HZ4 through the FUV line_20: prism combined with F140M and through the NUV prism combined with F195W. These line_21: exposures will also provide information on the filter red-leaks. ! question: 3 section: 3 line_1: CONTINUATION OF COMMENTS FROM EXPOSURE LOGSHEET: line_3: 15. THESE OBSERVATIONS ALSO PROVIDE A CHECK OF THE PRISM OFFSET VALUES line_4: (REQUIRED FOR "SEQD". SEQD IS THE PHOTOMETRIC CALIBRATION. THE TARGET line_5: POSITION FOR 7 AND 8 MAY HAVE TO BE REVISED AFTER PRELIMINARY ANALYSIS line_6: OF 1-3. HENCE SEQD SHOULD BE SCHEDULED LATER IN SV. ! !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: 2 name_1: LB227 name_2: GSC1255-744 descr_1: A; 120; J; 702 pos_1: RA=04H 09M 28.76S +/- 0.1S, pos_2: DEC=17D 07' 54.4" +/- 1", pos_3: PLATE-ID=000O equinox: 2000 pm_or_par: N plate_req: N fluxnum_1: 2 fluxval_1: V=15.35, TYPE=DA4 ! targnum: 3 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: 10 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 !
