abstract:

    line_1:        This proposal defines the long term sensitivity monitoring
    line_2:        program for the Goddard High Resolution Spectrograph. It
    line_3:        uses three UV standard stars, BD+28d4211, and BD+75d325.
    line_4:        1) BD+28d4211 will be the long term standard,
    line_5:        and will allow cross-calibration with FOS.
    line_6:        2) BD+75d325 will provide backup during SMOV and
    line_7:        will be observed as a close-out in Cycle 3.
    line_8:        3) AGK+81d266 will be observed to provide a baseline
    line_9:        for the SMOV focus test.
    line_10:       The exposure times are short and the medium resolution
    line_11:       gratings will be used with the LSA.

  question:        2
    section:       1
    line_1:        The sensitivity of the GHRS is likely to change slowly with
    line_2:        time, as the optics and detectors experience prolonged
    line_3:        exposure to the space environment. Accurate sensitivity
    line_4:        curves are needed for planning exposure times before an
    line_5:        observation, and for reducing data after the fact. A simple
    line_6:        program is needed to monitor and update the sensitivities
    line_7:        by making observations of UV standard stars several times per
    line_8:        year.

    line_1:
    line_6:        G160M,G200M,G270M:
    line_7:        Onboard acq with A2, LSA peakup, LSA image
    line_8:        med res spectra at 1200, 1500, 2000, 2500, 3000 LSA

  question:        5
    section:       1
    line_1:        Exposure times are based on observed count rates.
    line_2:        The goal is to obtain between 1000 - 10000 cts/diode in
    line_3:        each substep bin. High S/N is required to identify small
    line_4:        changes in sensitivity. Bright stars are used to keep the
    line_5:        total test time as short as possible. The same star is
    line_6:        used for all gratings to allow easy intercomparison and
    line_7:        cross calibration.
