abstract:

    line_1:        We propose using the FOS to examine the sightlines of QSOs which lie
    line_2:        fortuitously behind galaxies whose existence is already known, and whose
    line_3:        properties are easily discerned.  We have selected 7 QSOs background to
    line_4:        galaxies with which to study the Lya, MgII and C~IV absorption
    line_5:        cross-sections of modern-day galaxies using HST and the FOS.  This number will
    line_6:        provide a statistically significant set of sightlines through the disks and
    line_7:        haloes of many types of galaxies situated in many types of environment.  The
    line_8:        number studied and the equivalent width limits achieved will facilitate a
    line_9:        direct comparison with higher-redshift optical studies. We will also provide
    line_10:       important information on the question of how galaxies contribute to the Lya
    line_11:       forest lines now found at all redshifts.

  question:        3
    section:       1
    line_1:        We have selected 7 QSOs behind low-redshift galaxies. Exposure times
    line_2:        are based on obtaining 3 sigma equivalent width limits of 0.3A or better at the
    line_3:        better at the wavelength of the expected CIV/MgII absorption. Lya will
    line_4:        also be detected at larger equivalent width limits, usually ~0.5A.
    line_5:        Fluxes for 5 of 7 QSOs are known from IUE spectra, so the exposure
    line_6:        times for these data should be correct. Though sub-steps of 4 will be
    line_7:        used, the equivalent width limits are based on values after rebinning
    line_8:        to 2 pixels/diode. For QSOs without known fluxes, exposure times are based
    line_9:        on published V mags and assumption of a power law with alpha=-1. Background
    line_10:       count rate of 0.01 counts/sec/diode is used. Count rates are calculated f
    line_11:       from efficiency curves available on STEIS, and transmission of 0.9 is as
    line_12:       used for 1.0 aperture.
    line_14:       ACQ/BINARY has been selected for QSOs with known fluxes and exp. times
    line_15:       calculated using software available to the FOS Instrument Scientists.
    line_16:       For QSOs without known fluxes, a 3 stage ACQ/PEAKUP has been chosen,
    line_17:       using the 4.3, the 1.0 and the 0.5 apertures. Scans of 3x1, 6x2 and 3x3
    line_18:       have been selected for each aperture respectively. SCAN-STEPS have been
    line_19:       taken from the examples in thr FOS manual.
    line_21:       4 of the QSOs are side switched, such that the QSO is acquired, observed
    line_22:       with one grating/detector then switched to the other grating/detector.

    line_1:        4 of the QSOs are side-switched, such that the QSO ia acquired, observed
    line_2:        with one detector/grating then observed immediately after with the other
    line_3:        detector/grating. This means that these small subgroups should be observed
    line_4:        in sequence. This requirement has been entered on the exposure logsheets.
