abstract:

    line_1:        This proposal defines observations to be carried out in
    line_2:        the cycle 4 calibration program to verify use of GHRS mirror
    line_3:        N1 for target acquisition, and to reestablish the sensitivity
    line_4:        calibration for low resolution grating G140L. We use the UV
    line_5:        standard star BD+28d4211, perform target acquisitions with
    line_6:        mirror N1, and record the spectra with grating G140L at
    line_7:        central wavelengths of 1200, 1400, 1600 and 1800 A. The
    line_8:        exposure times are long enough to provide approximately
    line_9:        1000 cts per diode in each of four spectral bins at most
    line_10:       wavelengths. Spectra are taken with both the LSA and the SSA.

  question:        3
    section:       1
    line_1:        The observations are a straightforward use of N1 and G140L
    line_2:        lines 100,110 rtb search and lsa peakup
    line_3:        (I expect roughly 10000 cts/sec for this target and N1)
    line_4:        lines 120,130 image mode maps to confirm centering and
    line_5:        measure 2d image shape with N1 with costar in place.
    line_6:        lines 140-170 simple accums at 4 central wavelengths
    line_7:        fluxes from Bohlin's UV standards documents
    line_8:        lsa sensitivities from GHRS instrument handbook version 4.0
    line_9:        line 200 ssa rtb peakup
    line_10:       lines 210-240 same 4 accum spectra with star in ssa

  question:        5
    section:       1
    line_1:        This proposal should be scheduled for execution after the
    line_2:        carrousel commanding verification test has been run and
    line_3:        analyzed. Parameters for the target acquisition data bases
    line_4:        will need to be updated before this test will run. Execute
    line_5:        after successful execution of proposal 5277 and AFTER
    line_6:        installation/alignment of the COSTAR/GHRS mirror.

!

  question:        7
    section:       1
    line_1:        Deflection calibrations from the acquisitions will be analyzed
    line_2:        to refine the onboard target acquisition data bases.
    line_3:        Target acquisition fluxes will be checked for N1 sensitivity.
    line_4:        LSA and SSA sensitivity curves will be derived from measured
    line_5:        count rates and tabulated UV fluxes for this star.
    line_6:        This proposal does not use fp-splits, or obtain very high
    line_7:        S/N, so details of granularity and blemishes will not be
    line_8:        well measured.
