Intermediate/low resolution standards will be observed with line_3: the G140L, G140M, G160M, G200M, and G270M grating. line_4: One of the two primary objects is an FOS calibration star; line_5: This is the only proposal that will provide cross-calibration line_6: of GHRS and FOS. Primary purpose is to provide time history line_7: with two independent external sources. line_8: An independent CAL proposal with the brighter star mu Col line_9: as target will be used to monitor flux differences between line_10: LSA and SSA and at a higher density of wavelengths. ! ! end of abstract general_form_proposers: lname: DUNCAN fname: DOUGLAS mi: K. inst: ST SCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Observe BD+75D325 and HD 93521 as follows: line_2: 1. Acquire target using on-board acquisition. line_3: 2. Center in LSA and make focus diode aperture map. line_4: 3.
