abstract:

    line_1:        Four contrasting clusters are studied, to elucidate the differences in their
    line_2:        dynamics. Omega Centauri and 47 Tucanae are normal clusters but differ in
    line_3:        relaxation time by a factor of 30; they should show interesting differences of
    line_4:        structure due to differences in anistropy and equipartition. NGC 6624 has a
    line_5:        collapsed core, which has never been resolved. NGC 6752 is a concentrated
    line_6:        cluster with a small distance modulus and can be studied quite faint. Each
    line_7:        cluster is observed in B and V at the center and at 1 and 3 core radii;
    line_8:        ground-based data will be secured to carry the distributions farther out. The
    line_9:        distributions of all types of stars should be delineated, down to and including
    line_10:       red dwarfs and white dwarfs.
    line_12:       Far-UV exposures are made at the centers of M15 and NGC 6624, to search for
    line_13:       possible counterparts to the X-ray sources, and in the NGC 6752, to determine
    line_14:       the temperatures of the BHB stars.
    line_16:       Simultaneous exposures are made in V and I with the WFC, to gain further
    line_17:       structural information.

    line_3:        f/96, F430W, 1500 s (par. WFC, F785LP)

    line_1:        Relative roll angles specified for each exposure.
    line_3:        These ST observations are to be supplemented by ground-based CCD exposures in
    line_4:        the outer parts of the clusters; many exposures will be stacked, in order to
    line_5:        reach about the same limiting magnitude.

    section:       1
    line_1:        Roll angles are specified in such a way as to place WFC on same field for all
    line_2:        exposures made on a cluster.

  question:        13
    section:       1
    line_1:        Exposures at various radial distances will allow a study of the dynamics of the
    line_2:        clusters. Color-magnitude arrays including faint red dwarfs and white dwarfs.
    line_3:        The faint end of the BHB in NGC 6752 will be examined. The centers of M15 and
    line_4:        NGC 6624 will be examined in the UV for a possible identification of the X-ray
    line_5:        sources.
