7. Abstract
FOS spectra will be obtained for seven optically bright PG quasars [3C 273, PG
0953+415, PG 1116+215, PKS 1302-102, PG 1700+518, GQ Com, and 3C 249.1] with Mb </=
-25.0 mag and z </= 0.35, as well as V </= 15.7 mag. The spectra will be analyzed
for both absorption and emission features. ST observations are required because the
spectral features of greatest interest in these small redshift objects are in the
far ultraviolet, inaccessible from the ground.

  3. Description of proposed observations.
  Seven quasars will be observed with the FOS high dispersion gratings to study
 the absorption and emission lines. One object will be studied with the FOS low
 dispersion grating G160L in order to measure the ultraviolet flux for more
 detailed study will the higher dispersion gratings. The host objects in four
 quasars, targets 1-4, will be studied with the FOS and G650L.  Cycle 1(SV: 1-6
 months)= Exposures 1,2, 3,4,5,6,7,10,13,19,23,24,25.  Cycle 2(7-18
 months)=Exposures 8,9,11,12,13,14,15,16,17,18,20,21,26.  Cycle 3+4(19-30
 months)=Exposures 22.  For the low dispersion spectra of the host galaxy, we have
 provisionally chosen to offset the center of the aperture 1.2 arc seconds from
 the quasar position. The 1.0 square arcsecond aperture is to be offset 0.35
 arcseconds in RA and 0.35 arcseconds in DEC. The nearest corner of the aperture
 is 0.85 arcseconds from the DEC. We may decide to use the 2.0-BAR aperture if SV
 or Cycle 2 experience shows this is better.
------------------------------------------------------------------------------------
  4. Justification of need for HST observations.
  ST observations are required in order to reach the relevant ultraviolet
 wavelengths at which the quasar absorption and emission features occur. ST
 observations are required for the low dispersion spectra of the host galaxy
 because scattered light from the quasar prevents one from obtaining clean
 observations of the host galaxy from the ground.
------------------------------------------------------------------------------------
  6. Description of special calibration exposures.
  Parallel observations should be as long as possible (uinterrupted if scheduling
 permits) and in dark time (if scheduling permits).
------------------------------------------------------------------------------------
  7. Data reduction and analysis plans.
  Primary data reduction and analysis will be performed at IAS for the absorption
 line features and at KPNO for the emission line features.  The spectra of the
 quasar PG 1302-102 will be analyzed collaboratively with B. Savage (University of
 Wisconsin) to study absorption lines produced by intervening galaxies. An
 additional FOS observation of this object with FOS/BL and G130H will be obtained
 by Savage in his proposal entitled: "Absorption by Extragalactic Gaseous Halos."
------------------------------------------------------------------------------------
  8. Additional comments or special requests.
  Measurements in other wavelength regions will be acquired prior to ST launch in
 order to make the ST observations more meaningful. Many of the program objects
 have already been studied extensively by R. Green and his collaborators in
 connection with surveys taken in other wavelength regions. R. Green will obtain
 spectra in the visible at KPNO that are as nearly simultaneous with ST
 observations as scheduling permits and will combine the ST results and the new
 KPNO data with the original PG survey material. One arc second positions are
 being measured by R. Green for all of the program objects for all cases in which
 they are not already known.

------------------------------------------------------------------------------------
 10. Resources to be supplied by investigator's institution(s).
  Full computing support will be supplied by IAS. Reasearch associates will be
 available. Observing assistance and computing support will be provided KPNO for
 continuum and emission-line analyses.

  FOS spectra will be obtained for seven optically bright PG quasars (3C 273, PG
 0953+414, PG 1116+215, PKS 1302-102, PG 1700+518, GQ Com, and 3C 249.1) with Mb
 <=-25.0 mag and z<=0.35, as well as V<=15.7 mag. The spectra will be analyzed for
 both absorption and emission features.
