It makes use of the UV line_4: standard star Mu Columbae, with target acquisitions performed line_5: using mirror A2. The OSCAN mode is used to scan orders 18-31 line_6: at three carrousel positions that straddle the peak of the line_7: blaze function, with the star in the LSA. Only the peak of line_8: blaze will be scanned with the star in the SSA. ! ! end of abstract general_form_proposers: lname: HULBERT fname: STEPHEN inst: STSCI country: USA ! lname: SODERBLOM fname: DAVID inst: STSCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The star will be acquired with Mirror A2, using an RTB search line_2: a double locate, and two image mode maps. With the target line_3: well centered in the LSA a series of OSCAN exposures will be line_4: made to record orders 18-31 at three carrousel positions. line_5: These were selected to straddle the peak of the blaze line_6: function which is near m*lambda=56200. A substep pattern line_7: with four samples per diode width, and two background bins line_8: is used. line_13: After completion of the LSA exposures an line_14: RTB peakup will center the target in the SSA. An OSCAN line_15: sequence will measure the cont rates near the center of the line_16: blaze. line_17: Exposure times are short as the spectra will be binned line_18: into 5 A pieces. ! question: 7 section: 1 line_1: The primary goal is to compare the observed count rates line_2: with the tabulated standard fluxes to derive the Echelle line_3: sensitivity function. This will be used to help plan line_4: exposure times for future observations, and to reduce raw line_5: data. Better determination of the peak of the blaze function line_6: for Echelle B should also be possible. Comparison of the line_7: throughputs for the LSA and SSA will be made. Interorder line_8: and Echelle scattered light will be examined. ! !end of general form text general_form_address: lname: HULBERT fname: STEPHEN category: PI inst: STScI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: 410 338 4911 ! lname: SODERBLOM fname: DAVID category: CON inst: STScI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: 410 338 4543 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: MU-COL descr_1: J,702 pos_1: RA = 5H 45M 59.92S +/- 0.5S, pos_2: DEC = -32D 18' 22.8" +/- 0.3", pos_3: PLATE-ID=01WB equinox: 2000 pm_or_par: Y pos_epoch_bj: B pos_epoch_yr: 1950.00 ra_pm_val: 0.004000 ra_pm_unct: 0.004000 dec_pm_val: -0.0250 dec_pm_unct: 0.0030 fluxnum_1: 1 fluxval_1: V=5.17, TYPE = 09.5IV, E(B-V)=0.02 fluxnum_2: 2 fluxval_2: F-CONT(1200)=1.5 E-9 fluxnum_3: 3 fluxval_3: F-CONT(1500)=1.9 E-9 fluxnum_4: 4 fluxval_4: F-CONT(1700)=1.2 E-9 ! ! end of fixed targets !
