abstract:

    line_1:        The nucleus of M15 is imaged in the U band
    line_2:        to study the core properties and the existance of a collapsed cusp if any.
    line_3:        This is a test of image deconvolution and reconstruction in a crowded
    line_4:        field.  Excellent ground-based images of this field also exist and will
    line_5:        be compared.  The exposure sequence is repeated once at a slightly
    line_6:        different pointing.  Exposures are taken in NGC188 in Prop 3014 to determine
    line_7:        the point-spread function.

  question:        3
    section:       1
    line_1:        Exposures of various lengths are taken of the center of the cluster
    line_2:        M15 in F336W.  The U filter is used to select turnoff G dwarfs and
    line_3:        suppress the bright red giants.  The cluster was originally included
    line_4:        in the WFPC GTO program as a core collapse cluster.  Its inclusion
    line_5:        in the SAT program will provide UV images in an extremely crowded
    line_6:        region for which excellent-quality, good-seeing groundbased data
    line_7:        (taken with the NTT at ESO) also exist.  It is a good test of the
    line_8:        imaging capabilities of HST.

  question:        4

    line_1:        Instrument calibration.

  question:        5
    section:       1
    line_1:        The point-spread function sequence in NGC188 in 3014 should be taken near in
    line_2:        time to M15; the secondary mirror focus and collimation should
    line_3:        not be changed between these observations.  The camera should be UV-
    line_4:        flooded (if we are using a flood), and the interim telescope collimation
    line_5:        and focus adopted.

  question:        6
    section:       1
    line_1:        Avoid the SAA for all exposures.

!

  question:        13
    section:       1
    line_1:        Ultraviolet exposures in the nucleus of M15 will be
    line_5:        made to investigate the near-UV imaging properties of HST.
