abstract:

    line_1:        Among the globular clusters that have collapsed cores,
    line_2:        M15 is the strangest.  The sharp rise of velocity dispersion
    line_3:        observed near its center indicates either that it is in the
    line_4:        act of collapse or that it has a black hole at its center.
    line_5:        No one knows how small its true core is.  The high resolution
    line_6:        of the FOC f/96 camera offers the best opportunity to
    line_7:        "resolve" these problems.

  question:        3
    section:       1
    line_1:        On the central region of M15, near-UV imaging,
    line_2:        f/96, F342W, 1500 s
    line_3:        to lesen saturation at the center, an additional exposure:
    line_4:        f/96, F342W+F2ND, 600 s
    line_5:        The choice of near-UV is to suppress the bright stars as
    line_6:        much as possible.

    section:       2
    line_1:        It is assumed that PSF's will be available without the need to add
    line_2:        observations to this program to secure them.

  question:        7
    section:       0
    line_1:        At Berkeley we have a VMS cluster and a Sun cluster.  I have a
    line_2:        Microvax II GPX and a Sun IPC with a gigabyte disk.  For software we
    line_3:        have been using Vista, DAOPHOT, and IRAF/STSDAS.  Although it is an
    line_4:        unhappy fact that no one has yet arrived at the ideal method of
    line_5:        doing stellar photometry on HST images, I am doing at least as well
    line_6:        as anyone else and am in contact with most of those who are making
    line_7:        efforts in this direction.

    line_1:        Previous HST observing time:
    line_3:        SAO-3121, MORPHOLOGY OF FAINT GALAXIES - PART II
    line_4:        GTO-1277, IMAGING OF M31-GROUP GALAXIES

    line_9:        GTO-1282, IMAGING OF HIGH-REDSHIFT FIELD GALAXIES AND CLUSTERS
    line_10:       GTO-3217, (continuation of 1280)
    line_11:       GTO-3218, (continuation of 1279)
    line_12:       GTO-3219, (continuation of 1277)
    line_13:       GTO-3325, (continuation of 1279, 3218)
    line_15:       1279 is closely related to this proposal, which is intended to
    line_16:       bring the aggregate up to a critical mass.

  question:        9
    section:       2
    line_1:        Main results from previous related programs:
    line_3:        3121 produced a report that I am told was quite useful to the Cycle
    line_4:        1 Re-TAC, and also the publication below.
    line_6:        Otherwise all I have gotten up to now is a pair of exposures on the
    line_7:        center of Omega Centauri, which are in the early stages of
    line_8:        reduction, as well as the center of M32 and of the collapsed-core
    line_9:        globular cluster NGC7099,likewise under reduction.
    line_11:       In Cycle 1 I have put all of 1281 and all of the 1279 exposures on
    line_12:       NGC6624.
