abstract:

    line_1:        Two goals of this program are (1) to improve our knowledge
    line_2:        of the stellar population in elliptical galaxies, and (2)
    line_3:        to determine more exactly the distance of the Coma Cluster
    line_4:        and the implied value of the Hubble constant.  Luminosity
    line_5:        fluctuations based on pixel statistics will permit the top
    line_6:        of the H-R diagram and the top of the stellar luminosity
    line_7:        function to be better characterized than possible with
    line_8:        groundbased data, while luminosity functions of globular
    line_9:        clusters in ellipticals will help pin down the distance of
    line_10:       the Coma Cluster (z = 0.023).

  question:        3
    section:       1
    line_1:        On one flank of each elliptical galaxy, long WFC exposures
    line_2:        (~2000 seconds) will be made through two wide-band filters
    line_3:        (F555W and F814W). Each such pair of frames will span at
    line_4:        least the range from V = 22 to 25 mag arcsec**(-2), and a
    line_5:        second pair of frames (in some cases) will sample the
    line_6:        neighboring field.

!

  question:        6
    section:       1
    line_1:        Uninterrupted exposures (except for CR-splitting) are needed
    line_2:        to maximize S/N.  For all exposures exceeding 500 sec, we
    line_3:        request dark time in order to minimize scattered light.  By
    line_4:        dark time we mean that the telescope should be beyond the
    line_5:        brightly lit limb of the Earth in the dark half of the
    line_6:        orbit.  We do not require that the telescope actually be
    line_7:        within the Earth's shadow.

  question:        13
    section:       1
    line_1:        Long WFC exposures in two broad passbands will be obtained
    line_2:        on the flanks of large elliptical galaxies (plus M32) to
    line_3:        probe the top of the H-R diagram in the nearest ones and to
    line_4:        investigate the luminosity function of their globular
    line_5:        clusters. The latter will be used to help infer the distance
    line_6:        to the Coma Cluster, which has implications concerning H_o.
    line_7:        The primary targets are NGC 3379, 4649, 4881, and 221.
