abstract:

    line_1:        Whenever the automatic scheduler produces a substantial gap
    line_2:        between observations, the Wide Field/Planetary Camera will
    line_3:        be used to image a nearby object selected from a list of
    line_4:        several hundred low redshift quasars, normal galaxies,
    line_5:        peculiar galaxies, and standard survey fields.  HST
    line_6:        observations will reveal details of the immediate
    line_7:        environment of quasars, the nuclei of normal galaxies, the
    line_8:        morphology of peculiar galaxies, and the star density in
    line_9:        selected fields.  The purpose of this program is to increase
    line_10:       the efficiency of the HST and to provide scientific data
    line_11:       that can be used by many different astronomers.  The images
    line_12:       acquired in this program will be non-proprietary and will be
    line_13:       made available to qualified astronomers via the HST archival
    line_14:       system.  With the approval of the Director of STScI, the
    line_15:       images can also be used for public relations purposes by
    line_16:       appropriate NASA anad STScI personnel.

  question:        3
    section:       1
    line_1:        Images drawn from a set of several hundred targets will be
    line_2:        taken with the Wide Field/Planetary Camera whenever there is
    line_3:        a substantial time gap between previously scheduled
    line_4:        observations.  The images will be taken through either the
    line_5:        F555W or F785LP filters, and the exposure length will be the
    line_6:        maximum time that can be allowed without impacting the
    line_7:        scheduled observations.  No relative priorities have been
    line_8:        given to the individual observations as the order of
    line_9:        observation will be decided solely by whichever target will
    line_10:       produce a minimum of HST motion when an unscheduled block
    line_11:       of time occurs.

!

  question:        4
    section:       1
    line_1:        This proposal is designed to increase the efficiency of the
    line_2:        HST.

!

  question:        5
    section:       1
    line_1:        The exposure time for each observation will depend upon the
    line_2:        amount of unscheduled HST time.  For convience in scheduling,
    line_3:        each target will be assigned two exposures.  The number of
    line_4:        objects (several hundred) means that, on average, the
    line_5:        distance from a random HST orientation and the nearest
    line_6:        target is of the order of 10 degrees.

!

  question:        7
    section:       1
    line_1:        Data will be stored in the HST archive system and made
    line_2:        available on a non-proprietary basis to anyone authorized by
    line_3:        STScI who wishes to use the images for astronomical research.
    line_4:        On special occasions, the Director of STScI may decide that
    line_5:        some of the images may be used by NASA personnel or
    line_6:        authorized scientists.

!

  question:        8
    section:       1
    line_1:        Targets must be examined on the GSSS display system to make
    line_2:        certain that there are no unacceptably bright stars in the
    line_3:        field.  This will be done by J. Bahcall and D. Schneider
    line_4:        with appropriate STScI support.
