The goal of the test is to achieve S/N line_3: = 35 to 50A at 5A resolution. The star is an HST ultraviolet standard, and it line_4: is also a near-solar analog. The purpose of the test is to measure the amount line_5: of red leak into the ultraviolet region for an object with a color that is very line_6: similar to solar system objects. The information is necessary for efficient line_7: planning. ! ! end of abstract general_form_proposers: lname: CALDWELL fname: JOHN title: PROF inst: YORK UNIVERSITY country: CANADA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The complete spectrum will be observed by the FOS with two grating line_2: settings: G270H (2 min), G190H (15 min) and G160L (3 min). The line_3: complete spectrum will be observed by the HRS as follows: line_4: G140L, 1 setting, 80 min.; G200M, 12 settings, 58 min; line_5: G270M, 23 settings, 18.6 min. ! question: 5 section: 0 line_1: Scheduling comment from line 1: Since this star (HD186427) is an HST UV line_2: standard, it may have been visited before this test and exposure 1 may not be line_3: needed. line_5: SV Prerequisites: line_6: This test is to be performed after functional verification of target line_7: acquisitions in - line_8: FOS-02 COMBINED MODE II TARGET ACQUISITION (PROP 2195) line_9: HRS-05B MODE II TARGET LOCATE TAR ACQ (PROP 1352) line_10: and initial spectral calibration in - line_11: FOS-13 INTERNAL/EXTERNAL WAVELENGTH CAL (PROP 1317) line_12: HRS-10 INTERMEDIATE RESOLUTION CAL (PROP 1356) ! question: 7 section: 1 line_1: The data from the two spectrographs will be calibrated. For the HRS, the line_2: data will be binned to 5A resolution. The spectra will be plotted on the same line_3: scale. It is expected that the FOS will be systematically high because of the line_4: red leak, with the effect being much worse at shorter wavelengths, particularly line_5: below 2000A. line_7: Previous experience with OAO-2 and IUE data indicates that a line_8: wavelength-independent ("grey") correction may be sufficient to eliminate the line_9: red leak over much of the ultraviolet part of the FOS range. Such an approach line_10: will be tried with HST data first. If more sophisticated corrections are line_11: needed, these data will be used to determine the details. The worst case, that line_12: the data are not correctible, would still contain useful (but discouraging) line_13: information: that the HRS must be used for all ultraviolet spectra of red line_14: objects. This information is absolutely required to plan for planetary and line_15: late-type stellar spectra with the HST. ! !end of general form text general_form_address: lname: CALDWELL fname: JOHN title: PROF. category: PI inst: YORK UNIVERSITY addr_1: PHYSICS DEPT. addr_2: 4700 KEELE STREET city: NORTH YORK zip: M3J 1P3 country: ONTARIO, CANADA phone: 416-736-2100 X7721 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: 16CYGB name_2: HR7504, HD186427 descr_1: HST STANDARD UV CALIBRATION TARGET; ALSO S descr_2: OLAR ANALOG STAR pos_1: RA = 19H 41M 51.96S +/- 0.1S, pos_2: DEC = +50D 31' 02.9" +/- 1" equinox: 2000 pm_or_par: Y pos_epoch_yr: 1950.00 ra_pm_val: -0.000973 ra_pm_unct: 0.000200 dec_pm_val: -0.1600 dec_pm_unct: 0.0030 comment_1: FLUX DATA ARE FROM A SET comment_2: OF CALIBRATED IUE comment_3: SPECTRA OF THIS STAR OBTAINED BY comment_4: THE P.I. fluxnum_1: 1 fluxval_1: V=6.20 ! ! end of fixed targets !
