abstract:

    line_1:        FOC f/96 exposures will be taken in B and V, 1 hr each,
    line_2:        near the center of NGC 6397.  The aim is to determine a faint
    line_3:        color-magnitude array, as well as a faint luminosity function and
    line_4:        the relative density distribution of faint stars of different
    line_5:        magnitudes.  This program should go very much fainter than 3218,
    line_6:        since in addition to the COSTAR gain the former 3ND can be removed.
    line_7:        (The ND were needed in order to avoid saturation due to the diffuse
    line_8:        light of the overlapping spherical-aberration halos.)
    line_9:        Short ND exposures will be taken, in order to get the brighter stars
    line_10:       without saturation.  A short F275W exposure will be taken, to
    line_11:       lengthen the color baseline for the X-ray source, which becomes
    line_12:       prominent in the UV.  If an INT ACQ is needed, it will be taken
    line_13:       through F342W, so as further to increase the color information.

  question:        3
    section:       1
    line_1:        We take a 2-orbit exposure in F430W and in F480LP, so as to get a
    line_2:        deep CMD in conventional color bands.  The two bands can be used to
    line_3:        synthesize a 2-color picture (feeding the intermediate-color gun
    line_4:        with the mean of the two).  A fifth orbit is used to get 3 short
    line_5:        exposures: 10-min F430W and F480LP to get the brighter stars that
    line_6:        were saturated on the long exposures, and an F275W to broaden the
    line_7:        color baseline for the X-ray source.  (Going shorter would show
    line_8:        nothing but the X-ray source.)  In case it is needed, an INT ACQ is
    line_9:        put in at the beginning; it is done with F342W and will increase the
    line_10:       scientific information.

  question:        9
    section:       1
    line_1:        Proposal 3218 took this field (and 2 others) in NGC 6624 in F430W
    line_2:        and F480LP, in each case with 3ND.  Photometry is complete, and
    line_3:        color-magnitude diagrams were presented at an AAS meeting.  In 3218
    line_4:        there was also an F140W image, which discovered the optical
    line_5:        counterpart of the X-ray source (ApJ Letters, in press).  This star
    line_6:        was easily seen in F430W but was invisible in F480LP.  It will now
    line_7:        be visible in both bands.
