abstract:

    line_1:        Obtain data on the stellar populations in the central cores of globular
    line_2:        clusters. Clusters with and without central unresolved cusps, and with and
    line_3:        without central X-ray sources will be observed. Spectra will be obtained at
    line_4:        the center of the UV brightness, and at a distance within about one core
    line_5:        radius. We might expect these spectra to differ; massive objects formed in
    line_6:        collisions may produce unexpected spectral features, as well as relatively
    line_7:        intense UV radiation in the central core.

  question:        3
    section:       1
    line_1:        Since the globular clusters are faint, use the low dispersion G160L and
    line_2:        the Prism on the Blueside. Use the lower 0.3" aperture.
    line_3:        The PC images are essential for target acquisition for the spectra.
    line_4:        Offset the PC pointing to place the center of the G.C. (quoted coordinates)
    line_5:        10" off the pyramid along the centerline of the best CCD chip. We require two
    line_6:        months between delivery of the PC images and the final specification of the FOS
    line_7:        pointings. FOS target acquisition in mode III assumes that the PC is
    line_8:        calibrated for astrometry to 0.03".
    line_9:        PC filters are F230W, F336W, and F547M.
    line_10:       Cycle 2: 204-205, 209-220
    line_11:       Cycle 9: 901-904

  question:        5
    section:       2
    line_1:        The SV prerequisite programs for all FOS
    line_2:        observations in this program are:
    line_3:        Prop ID 2195 FOS Target Acquisition Tests
    line_4:        - All observations
    line_5:        Prop ID 1317 Int./Ext. Wavelength Offsets
    line_6:        - 1st target
    line_7:        Prop ID 1318 Spectral Flat Fields
    line_8:        - 1st target
    line_9:        Prop ID 1320 Absolute Spectrophotometry
    line_10:       - 1st visit of bright targets
    line_11:       All WF/PC imaging with a center wavelength
    line_12:       blueward of 5000 Angstroms requires UV flood

!

  question:        12
    section:       1
    line_1:        This program does not become a viable scientific investigation until 5 of the 6
    line_2:        globular clusters have been observed by both the WFPC and FOS. No data should
    line_3:        be made public sooner than 1 year after that time.

!

  question:        13
    section:       1
    line_1:        Use FOS spectra to investigate the structure and dynamics of the cores of
    line_2:        globular clusters. Spectra on and just off the core will be obtained for
    line_3:        clusters with and without cusps and with and without central x-ray sources.
