abstract:


    line_1:    Direct images of the nuclei of nearby galaxies taken with the
    line_2:    Planetary Camera will be used to measure the space density 
    line_3:    profile of luminous material and the nuclear color gradients in 
    line_4:    these objects. Galaxies will be imaged with the F555W and F814W 
    line_5:    filters. Serveral objects known to contain ionized gas will also
    line_6:    be imaged in narrow-band filters to obtain the gas distribution. 
    line_7:    In M31 and M32 a special series of ultra-violet exposures will 
    line_8:    be taken to study the hot stellar population. The sample of 
    line_9:    objects contains several normal ellipticals covering a broad 
    line_10:   range in nuclear surface brightness and concentration class, 
    line_11:   several nearby galaxies covering a range of Hubble types, and a 
    line_12:   few Seyfert and otherwise slightly abnormal nuclei.  The images 
    line_13:   taken will also be searched for bright stars, inner globular 
    line_14:   clusters, and absorbing interstellar dust.
    line_15:   The far UV exposures in M31 and M32 are designed to discover
    line_16:   the source of the the far-UV upturn in the light of old
    line_17:   stellar populations.  The brightness and luminosity function
    line_18:   of any point sources will be measured, along with the brightness
    line_19:   and distrubution of the diffuse background light.

  question:        3
    section:       1
    line_1:        Direct exposures are proposed with the Planetary Camera and filters F555W and
    line_2:        F814W of duration 26 sec to 1800 sec. Desired S/N is 100 in the central pixel.
    line_3:        Shorter/multiple exposures are included for cosmic ray removal and possible 
    line_4:        stellar nuclear components. Special UV exposures of M31 are also proposed 
    line_5:        with F160BW and F300W filters.  Dithers are specified in
    line_6:        several of the M31 exposure sequences, to allow better
    line_7:        discrimination of chip problems and true sources.

!

  question:        5
    section:       1
    line_1:        For many objects, an exposure sequence has been designed that is intended to
    line_2:        fit within one orbit. Such objects are designated by the special requirement
    line_3:        "SEQ X-Y WITHIN 50 m NO GAP". The purpose of this requirement is to ensure
    line_4:        that all exposures register as well as possible, hence the request that the
    line_5:        telescope not be slewed between exposures. In no case does the exposure
    line_6:        sequence extend beyond 50m (one orbital opportunity).

!

  question:        6
    section:       1
    line_1:        Limiting noise source is readout noise; exposures should not be interrupted.

!

  question:        13
    section:       1
    line_1:        Nuclear luminosity distributions and color gradients will be studied in 33
    line_2:        nearby galaxies using filters F555W and F814W and the Planetary Camera.
    line_3:        Narrow-band images will also be taken of nuclei containing interstellar gas.
    line_4:        Images will be searched for bright stars, globular clusters, and interstellar
    line_5:        dust. UV exposures of M31 using the WFC will be used to study hot stars in the
    line_6:        stellar population in the nuclear bulge.
