abstract:

    line_1:        The evolution of Lyman-alpha and CIV absorption line systems
    line_2:        in quasar spectra will be investigated using 21 optically
    line_3:        bright quasars with a wide range of redshifts; the
    line_4:        wavelength at which the Lyman cutoff appears will also be
    line_5:        determined. All of the prominent emission and absorption
    line_6:        lines will be measured. ST observations are required because
    line_7:        the spectral features of interest are in the far ultraviolet
    line_8:        and are inaccessible from the ground.

  question:        3
    section:       1
    line_1:        Twenty-one quasars will be studied spectroscopically with
    line_2:        the FOS and the gratings G130H, G190H, G270H, G160L, and in
    line_3:        a few cases for comparison with ground-based observations,
    line_4:        G400H. Exposures are taken with a given grating only if the
    line_5:        data contributes to the statistical program of analyzing
    line_6:        absorption systems. Exposures 3, 22-24, and 34 will be used
    line_7:        to calibrate the procedure relative to ground based
    line_8:        observations of absorption lines. Exposures 3 and 22 should
    line_9:        be scheduled within one week of each other.  Parellel
    line_10:       observations will be made with the WF/PC for the longer
    line_11:       exposures to help determine the density of background
    line_12:       objects for the proposal: "Luminosity Functions and Tidal
    line_13:       Radii of Globular Clusters in Virgo," [J. Bahcall, P.I.].
    line_14:       Exposures 16-21 are parallel observations.
    line_15:       Cycle 1 (SV: 1-6 months)=Exposures 3,5,8,10,12,22,24
    line_16:       Cycle 2 (7-18 months)=Exposures 1,4,7,11,13,15,23,25-35
    line_17:       Cycle 3+4 (19-30 months)=Exposures 2,6,9,14,36-50
    line_18:       Exposures 3 and 22 should be taken within a few days of
    line_19:       each other.  Exposures 16-21 are parallel exposures.
    line_20:       Desirable but not critical.

!

  question:        4
    section:       1
    line_1:        ST observations are required to reach the far ultraviolet
    line_2:        wavelengths at which the relevant absorption and emission
    line_3:        lines occur. UM 18 (target 12) has been studied extensively
    line_4:        from the ground (Young et al. Ap. J. 252, 10, 1982), as have
    line_5:        S4 1435+63 and UM 402, and will be used to help calibrate
    line_6:        the ST reduction and analysis procedures relative to
    line_7:        standard ground based observations.

!

  question:        5
    section:       1
    line_1:        Exposures 3 and 22 should be scheduled within one week of
    line_2:        each other.  We want to compare the spectra obtained with
    line_3:        the two gratings with simultaneous ground-based observations
    line_4:        and detections of absorption lines. This comparison would be
    line_5:        complicated if the continuum emission of the quasar varied
    line_6:        during the period between exposure 3 and exposure 22.

!

  question:        6
    section:       1
    line_1:        Parallel observations should be as long as possible
    line_2:        (uninterrupted if scheduling permits) and in dark time (if
    line_3:        scheduling permits).

!

  question:        7
    section:       1
    line_1:        Primary data reduction and analysis will be performed at IAS
    line_2:        for the absorption line features and at KPNO for the
    line_3:        emission line features.

!

  question:        8
    section:       1
    line_1:        Measurements in other wavelength regions will be acquired
    line_2:        prior to ST launch in order to make the ST observations
    line_3:        more meaningful. Many of the program objects have already
    line_4:        been studied extensively by R. Green and his collaborators
    line_5:        in connection with surveys taken in other wavelength regions.
    line_6:        R. Green will obtain spectra in the visible at KPNO that are
    line_7:        as nearly simultaneous with ST observations as scheduling
    line_8:        permits and will combine the ST results and the new KPNO
    line_9:        data with the original PG survey material. One arc second
    line_10:       positions are being measured by R. Green for all of the
    line_11:       program objects for all cases in which they are not already
    line_12:       known. Targets 2, 11, 12, and 15 (exposures 3, 22-24, 34-35)
    line_13:       will be studied spectroscopically from the ground prior to
    line_14:       the launch of ST in order that we can compare our
    line_15:       sensitivity and reduction procedures to standard
    line_16:       measurements from the ground. For this reason, we have
    line_17:       requested observations of Targets 2, 11, and 12 in a
    line_18:       wavelength region that is also accessible from the ground.

!

  question:        10
    section:       1
    line_1:        Full computing support will be supplied by IAS. Research
    line_2:        associates will be available. Observing assistance and
    line_3:        computing support will be provided by KPNO for continuum
    line_4:        and emission-line analyses.

!

  question:        13
    section:       1
    line_1:        The evolution of Lyman-alpha and CIV absorption line systems
    line_2:        in quasar spectra will be investigated using 21 optically
    line_3:        bright quasars with a wide range of redshifts; the
    line_4:        wavelength at which the Lyman cutoff appears will also be
    line_5:        determined. All of the prominent emission and absorption
    line_6:        lines will be measured.
