A field map will be taken to line_3: measure the precise location in the aperture. The carrousel will then be line_4: rotated to position the desired grating at the chosen wavelength. Spectral line_5: lamp SC1 will be turned on and its spectrum will be recorded, including line_6: deriving a new SPYBAL offset. The spectrum of the star in the LSA will be line_7: recorded next. The star will then be translated to the SSA, and its spectrum line_8: will be recorded. It is important that the carrousel not be moved bwtween line_9: these three observations. After the SSA spectrum, the carrousel will be line_10: rotated to position the acquisition mirror, and a field map of the SSA will be line_11: obtained. After this map, the star will be returned to the center of the LSA. line_12: This sequence will be repeated at four or five wavelengths (carrousel line_13: positions) for each of the four medium resolution first order gratings. The line_14: spectrum will contain many deep and narrow interstellar absorption lines at line_15: each of the selected wavelengths. The precise locations of many lines will be line_16: compared to derive the offset of the LSA spectrum with respect to the SSA line_17: spectrum. The offsets will be calibrated for each grating as functions of line_18: carrousel angle and sample position. ! question: 4 section: 1 line_1: Offsets between the Small Science Aperture and the two Pt-Ne spectral lamps line_2: were established during the Phase 6 ground based calibration program. There line_3: was no easy way to center a point source in the Large Science Aperture, and line_4: offsets for the LSA were not measured. This test will use interstellar lines line_5: in a stellar spectrum observed through both apertures to derive offsets for the line_6: LSA relative to the SSA. ! question: 5 section: 1 line_1: OV/SV PREREQUISITES: line_2: Mode II Target Acquisition Target Locate (HRS-05.2) (Prop 1352) line_3: Spectral Lamp Mini-Functionals for Gratings (Props 1363-1367) line_4: Doppler Compensation - prop 1372 line_6: SV Minimum Plan: lines 19-19.8, 20-34, 38-46, 50-58 line_7: SV Delta Plan: lines 6-18, 35-37, 47-49, 59-61 line_8: Guiding Tolerance: 0.012 arc seconds line_10: ALTERNATE TARGET SELECTION: line_11: HD93521 is the prime target for this observation and is reflected in the line_12: Exposure Logsheets. HD93205 is an alternate that will be used if the prime line_13: target is not available or severely impacted by SAA overlap of its visibility line_14: period. ! question: 6 section: 1 line_1: None are requested. ! question: 7 section: 1 line_1: HD93521 is above the galactic plane, and its spectrum contains line_2: narrow absorption lines from the interstellar material. The line_3: observations of the SC1 lamp will establish a precise wavelength scale for the line_4: SSA at each carrousel position. The positions of many lines across the entire line_5: diode array will be measured in the stellar spectra observed through both the line_6: LSA and the SSA. The field maps of the apertures will provide information line_7: about the precise location of the star within each aperture. The observed line_8: offsets will be parameterized as functions of carrousel position and diode line_9: number (or sample). ! question: 8 section: 1 line_1: These observations should be scheduled fairly late in the SV program. Precise line_2: positioning of the star in both apertures is an important requirement. We will line_3: have more confidence in the calibration of the aperture locations in the V2, V3 line_4: coordinates, and in the ability of the target acquisition flight software to line_5: center the star properly towards the end of SV. ! question: 10 section: 1 line_1: 1.
