This proposal line_4: implements that decision. line_5: A measurement of the absolute sensitivity of the line_6: FOS detectors will be performed using theoretical line_7: pure hydrogen model atmosphere calculations for line_8: three white dwarfs. line_9: The high resolution gratings will be used line_10: in the 1 arcsec aperture. line_11: A four stage peakup of the standard star provides line_12: centering in the aperture. line_13: Observations are requested for fall 94 with repeated line_14: observations about two months after. general_form_proposers: lname: COLINA fname: LUIS title: P.I. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA lname: BOHLIN fname: RALPH title: C.I. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA lname: KEYES fname: CHARLES (TONY) title: C.I. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA lname: KORATKAR fname: ANURADHA title: C.I. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA lname: KINNEY fname: ANNE title: C.I. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA lname: TAYLOR fname: CYNTHIA title: C.I. inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA general_form_text: question: 2 section: 1 line_1: These measurements will provide the FOS absolute line_2: sensitivity. question: 3 section: 1 line_1: Spectra of three white dwarf standard stars will be obtained line_2: in five red detector and four blue detector-high dispersion line_3: grating combination. To assure registration of the spectrum line_4: on the diode array, the stars will be observed at 3 y-bases line_5: with an 0.156 arcsec (31.2 micron) separation. All spectra line_6: will be obtained in the 1.0 arcsec aperture. question: 5 section: 1 line_1: PREREQUISITES: line_2: 1) Pointing stability of 10% of the smallest aperture used line_3: (1.0") - 0.1" - is required. question: 7 section: 1 line_1: Data reduction will be performed at the STScI with the line_2: results used to update the RSDP inverse sensitivity files line_3: and to determine the full photometric recalibration of the line_4: FOS, particularly in the UV range, where the switch to the line_5: WD flux scale is up to 15% systematic change in flux scales. line_6: This new basis for absolute calibartion will also be line_7: propagated from FOS to all the SI's on HST. general_form_address: lname: COLINA fname: LUIS category: PI inst: STSCI addr_1: 3700 SAN MARTIN DRIVE city: BALTIMORE state: MD zip: 21218 country: USA phone: 410-338-5086 fixed_targets: targnum: 1 name_1: HZ43 name_2: GSSS1996-1402 descr_1: J,702 pos_1: RA = 13H 16M 22.0S +/- 0.01S, pos_2: DEC = +29D 05' 57.0" +/- 0.2", pos_3: PLATE-ID=002K equinox: 2000 comment_1: THE GSC NAME IS GIVEN. pm_or_par: Y pos_epoch_bj: J pos_epoch_yr: 1982.39 ra_pm_val: -0.0116 ra_pm_unct: 0.0002 dec_pm_val: -0.0813 dec_pm_unct: 0.0095 fluxnum_1: 1 fluxval_1: V = 12.68 +/- 0.02 fluxnum_2: 2 fluxval_2: B = 12.56 +/- 0.02 targnum: 2 name_1: GD71 name_2: LTT11733 descr_1: J,702 pos_1: RA = 05H 52M 27.5S +/- 0.01S, pos_2: DEC = +15D 53' 16.6" +/- 0.2", pos_3: PLATE-ID=009N equinox: 2000 pm_or_par: Y pos_epoch_bj: J pos_epoch_yr: 1982.96 ra_pm_val: 0.0047 ra_pm_unct: 0.0000 dec_pm_val: -0.1879 dec_pm_unct: 0.0000 fluxnum_1: 1 fluxval_1: V = 13.04 +/- 0.02 fluxnum_2: 2 fluxval_2: B = 12.80 +/- 0.02 fluxnum_3: 3 fluxval_3: U = 11.73 +/- 0.02 targnum: 3 name_1: GD153 name_2: GSSS1455-1145 descr_1: J,702 pos_1: RA = 12H 57M 02.4S +/- 0.01S, pos_2: DEC = +22D 01' 56.0" +/- 0.2", pos_3: PLATE-ID=01PN equinox: 2000 comment_1: THE GSC NAME IS GIVEN. pm_or_par: Y pos_epoch_bj: J pos_epoch_yr: 1982.38 ra_pm_val: -0.00145 ra_pm_unct: 0.0000 dec_pm_val: -0.1898 dec_pm_unct: 0.0000 fluxnum_1: 1 fluxval_1: V = 13.40 +/- 0.02 fluxnum_2: 2 fluxval_2: B = 13.17 +/- 0.02 exposure_logsheet: linenum: 1.000 sequence_1: DEFINE sequence_2: PTARG targname: # config: # opmode: ACQ/PEAK aperture: 4.3 sp_element: # num_exp: 1 time_per_exp: 1S priority: 1 param_1: SEARCH-SIZE-X=1, param_2: SEARCH-SIZE-Y=3, param_3: SCAN-STEP-Y=1.204 req_1: SEQ 1-3 NO GAP;
