7. Abstract
We propose WFPC2 observations of the fields of 17 quasars to investigate the
properties of the host galaxies and environments as functions of radio and optical
luminosity.  Recent results of a radio study of optically-selected quasars confirm a
previously-reported decrease in radio-loud fraction of quasars with absolute
magnitudes fainter than MB = -24.  The proposed HST observations have two purposes:
to determine whether there is a corresponding change in host galaxy and environment
properties for quasars fainter and brighter than MB = -24; and to compare these
properties for radio-loud and radio-quiet quasars.  The sample is selected from the
Large Bright Quasar Survey, a homogeneous survey compiled by an automated procedure
which is reasonably free of selection effects.  The HST observations will be
complemented by an ongoing ground-based imaging and spectroscopy program.

  3. Description of proposed observations.
  Each of 16 quasars will be placed within 100 pixels of the geometric center of
 the Planetary Camera, which will be used to image the host galaxy and any close
 neighbors.  The 3 CCDs of the Wide Field Camera will provide a view of any
 surrounding cluster environment which may be present.  B and R filters (F439W and
 F675W, respectively) will be employed.  The total exposure times were determined
 by the need to observe sufficient spatial extent in the host galaxies.  This was
 estimated from a model of a typical host galaxy, which is described in the Phase
 I proposal.  Since no a priori information is known about the galaxies in
 individual fields, the S_TO_N keyword in the exposure logsheet lines are left
 blank.  Quasars with redshifts in the range 0.4 < z < 0.45 are given 20 minutes
 (3 X 400 seconds) per filter.  The higher redshift objects (0.45 < z < 0.5) are
 typically given 25 minutes (3 X 500 seconds) per filter, although the R-band
 exposures for 3 objects are broken into 4 X 350 second (23.3 minute) segments to
 avoid blooming in the central pixel.  The R-band exposure time for one object had
 to be broken into 5 X 300 second exposures to reduce the chance of blooming.  The
 numerical saturation limit of 60000 electrons may be exceeded in the central
 pixels of the individual R-band images for eight quasars.  In these cases an
 additional 80 second unsaturated image will be obtained to aid in the
 deconvolution of the quasar from the host. The SEQ NO GAP special requirement has
 been set for each of the 80 second exposures to link them to the longer exposures
 of the same field.  This is necessary, since long time lags will introduce
 uncertainties due to detector changes or variability in the quasars.   The gain
 is set to 15 e-/DN for all exposures in both filters.  The specific exposures
 through the B filter are: 3 X 500 seconds for targets 4, 5, 10, 11, 12, 13, 16,
 17; 3 X 400 seconds for targets 1, 2, 3, 6, 7, 8, 9, 15.  Note that there is not
 a target number 14.  The specific exposures through the R filter are: 3 X 500
 seconds for target 17; 3 X 500 seconds plus 80 seconds for each field for targets
 4, 12, 16; 5 X 300 seconds + 80 seconds for target 10; 4 X 350 seconds for target
 13; 4 X 350 seconds plus 80 seconds for each field for targets 5, 11; 3 X 400
 seconds for targets 1, 2, 6, 7, 8, 9; 3 X 400 seconds plus 80 seconds for each
 field for targets 3, 15.
------------------------------------------------------------------------------------
  4. Justification of need for HST observations.
  The high angular resolution of HST is required for detailed imaging of the
 quasar hosts and surrounding galaxies.  Host galaxy parameters derived from
 ground-based images are rather uncertain, due to the difficulty of deconvolving
 the relatively large point spread function produced by atmospheric seeing.
 Typical seeing corresponds to a resolution of approximately 7 kpc at z = 0.5,
 whereas the Planetary Camera will be able to resolve structures roughly as small
 as 600 pc. The extensive ground-based observations which will support the HST
 data are discussed in the Scientific Justification (section 2) of the Phase I
 proposal.

  5. Description of special scheduling requirements.
                                                                  Page   3
------------------------------------------------------------------------------------
  6. Description of special calibration exposures.
------------------------------------------------------------------------------------
  8. Additional comments or special requests.
  The value for the APERTURE keyword is PC1 for every exposure, which requests
 that the target be placed at the optimum center of the PC. If this position will
 be more than about 100 pixels from the geometric center of the PC, please choose
 the best center within 100 pixels of the geometric center.  We do not want to
 lose any part of the quasar host galaxies or any close interacting galaxies off
 the edge of the CCD.
------------------------------------------------------------------------------------
  9. Description of previous HST work.
  GO Program 2524 "Spectropolarimetry of Bright Quasars" - IMPEY GO Program 3732
 "Spectropolarimetry of Bright Quasars" - IMPEY GO Program 3648 "Imaging of BL Lac
 Host Galaxies and Environments" - IMPEY GO Program 4402 "A Study of the
 Gravitational Lens 1422+321" - IMPEY, FOLTZ None are related to this proposal.
 Papers are in preparation on the results of GO Programs 2524 and 3732.  The data
 from GO Program 3648 have been received and are being reduced.  The observations
 for GO Program 4402 have not yet been made.
------------------------------------------------------------------------------------
 10. Resources to be supplied by investigator's institution(s).
  The University of Arizona will provide central computing services (hard disks,
 networks, tape drives) in support of this project.  We will also be supported by
 the University of Arizona in complementary ground-based observing of the quasar
 fields.
