Two standard stars will separately be placed at a line_3: number of different positions along the slit length to determine the line_4: sensitivity of the spectrograph--with respect to wavelength and to slit line_5: position. line_7: The experiment needs to be done for both echelle and filter modes. line_10: If necessary, the data will be used line_11: updating the SOGS RSDP calibration files. line_12: Real time downlink/uplink required. ! ! end of abstract general_form_proposers: lname: PARESCE fname: F. title: DR. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Standard stars will be placed on the slit, in both echelle and filter modes, line_2: and used to calibrate the photometric response of the f/48 spectrograph with line_3: wavelength. The standards have absolute flux measures from IUE and line_4: ground-based studies which in combination cover the required wavelength region line_5: from 1200-6000 A. The observed counts will lead directly to the derivation of line_6: a sensitivity curve. Comparison with the predicted OTA+FOC throughput for line_7: different wavelengths will enable any deterioration of FOC response to be line_8: measured and monitored. line_10: The targets will be placed at different positions along the slit. These line_11: spectra will yield the plate scale of the spectrograph and the photometric line_12: response of the spectrograph in the spatial direction. ! question: 5 section: 1 line_1: Real time observations are required to monitor positioning of the star with line_2: respect to the slit template and the slit. ! !end of general form text general_form_address: lname: PARESCE fname: FRANCESCO category: PI inst: ST SCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA ! ! end of general_form_address records fixed_targets: targnum: 2 name_1: LB227 descr_1: UV-OPTICAL STANDARD pos_1: RA=4H 9M 28.76S +/- 0.1S, pos_2: DEC=+17D 07' 54.4" +/- 1.0" equinox: 2000 fluxnum_1: 1 fluxval_1: V=15.35,TYPE= DA4 ! targnum: 3 name_1: HZ4 descr_1: ^ pos_1: RA=3H 55M 21.8S +/- 0.1S, pos_2: DEC=+9D 47' 18.1" +/- 1.0" equinox: ^ fluxnum_1: 1 fluxval_1: V=14.47,TYPE= DA4 ! targnum: 4 name_1: HZ21 descr_1: ^ pos_1: RA=12H 13M 56.42S +/- 0.1S, pos_2: DEC=+32D 56' 30.8" +/- 1.0" equinox: 2000 fluxnum_1: 1 fluxval_1: V=14.42,TYPE= DO1 ! targnum: 5 name_1: BPM16274 descr_1: ^ pos_1: RA=0H 50M 03.4S +/- 0.1S, pos_2: DEC=-52D 08' 19" +/- 1.0" equinox: ^ fluxnum_1: 1 fluxval_1: V=14.22,TYPE= DA2 ! targnum: 6 name_1: Q2000-330 descr_1: QUASAR pos_1: RA=20H 03M 24.12S +/- 0.1S, pos_2: DEC=-32D 51' 46.4" +/- 1.0" equinox: ^ fluxnum_1: 1 fluxval_1: V=17.6 ! ! end of fixed targets !
