abstract:

    line_1:        Observations with the WFPC2 will be used to construct color-magnitude
    line_2:        diagrams that precisely determine the magnitude and color of the
    line_3:        main-sequence turnoff and lower giant branch, and allow the ages
    line_4:        of 7 globular clusters to be derived.  Four are metal-rich clusters of
    line_5:        the disk population and three are very metal-poor clusters near the
    line_6:        galactic center.  Only the HST can provide the very high resolution
    line_7:        necessary for photometry to the required faint limits in the crowded
    line_8:        fields of these clusters.  The ages of the clusters will be measured
    line_9:        from the c-m diagrams using several techniques, and will be compared
    line_10:       with each other and with the ages derived for other clusters from
    line_11:       ground-based observations.  Our investigation will yield the first
    line_12:       chronology of the halo and thick disk clusters near the galactic
    line_13:       center, where star formation may have proceeded more rapidly than
    line_14:       in the outer, lower density regions.  Age differences > 3 Gys. are
    line_15:       now known to exist among the globular clusters in the outer halo,
    line_16:       and the addition of our results will indicate the timescales of
    line_17:       halo and disk formation as functions of galactocentric distance.
    line_18:       This will tightly constrain theories of the evolution of the Galaxy.
    line_19:       This proposal is a resubmission of a GO proposal that had to be
    line_20:       largely deferred until after the repair mission.

  question:        3
    section:       1
    line_1:        Our program is designed to obtain high-precision relative photometry for
    line_2:        all the stars in the WFPC2 fields.  This will allow us to determine
    line_3:        the mean positions of the cluster principal sequences with much
    line_4:        greater precision than the photometry of an individual star.  Since it
    line_5:        is the relative locations of these sequences that yield the differences
    line_6:        in cluster ages, our major goals can be achieved even if the zero points
    line_7:        of our photometry are difficult to determine.  The zero points are
    line_8:        unlikely to be a problem because they will be set by ground-based
    line_9:        observations (see below).
    line_10:       The PC chip of the WFPC2 will be used to photometer the regions of
    line_11:       highest stellar density, while the WFC chips will record the outer
    line_12:       regions and the star fields surrounding the clusters.  3 or 4 long
    line_13:       exposures per filter will be taken of a field close to the center of
    line_14:       each cluster.  The long exposures are designed to achieve S/N > 50 at
    line_15:       2 mag. below the expected turnoffs of the clusters, which should
    line_16:       enable us to achieve the required photometric accuracy in these dense
    line_17:       fields.  Three short exposures at the same positions will provide an
    line_18:       extension of the PC's dynamic range to brighter stars in the field
    line_19:       (horizontal branch & lower giant branch).  We will also take sets of
    line_20:       3 or 4 long and three short exposures per filter of fields offset from
    line_21:       the first ones by 20 arcsecs in the directions away from the
    line_22:       cluster centers.  These observations, which will overlap to some
    line_23:       extent with the central sets, will provide important additional

!

  question:        3
    section:       2
    line_1:        information on the principal cluster sequences.  Ground-based
    line_2:        photometry of the brighter stars in these more radially distant fields,
    line_3:        which will be possible given their lower densities, will provide the
    line_4:        calibration of the WFPC2 observations.  The WFPC2 observations will be
    line_5:        made with the F555W and F814W filters, for which straightforward
    line_6:        transformations to the V and I bands of the standard Cousins system
    line_7:        will be possible.  The WFC images of the area around each cluster and
    line_8:        ground-based observations of comparison fields outside the tidal radii
    line_9:        of the clusters will be used to assess the contamination of the
    line_10:       cluster fields by non-cluster members.

!

  question:        4
    section:       1
    line_1:        Members of our team have constructed c-m diagrams of three of our
    line_2:        targets using large ground-based telescopes under excellent conditions,
    line_3:        and have achieved only limited success.  Heasley, Janes, Christian, and
    line_4:        Montgomery (1993, in preparation) observed NGC 6293 with the CFHT and
    line_5:        its high resolution camera.  Although their data have extremely small
    line_6:        images for ground-based observations, 0.5 arcsec FWHM, severe image
    line_7:        crowding in the central region of the cluster limited the quality of
    line_8:        the photometry.  Accurate photometry was possible in the outer regions
    line_9:        of the cluster, but there confusion from numerous field stars limits
    line_10:       the precision to which the principal sequences of the clusters can be
    line_11:       defined.  The same problem was encountered by Fullton, Carney, and
    line_12:       Seitzer (1993 in preparation) in their investigation of NGC 5927,
    line_13:       which they observed in 0.8 arcsec seeing with the CTIO 4m telescope.
    line_14:       Again the central regions of the cluster were inaccessible and in the
    line_15:       outer regions, where faint photometry was possible, the c-m diagram
    line_16:       is swamped by field stars.
    line_17:       This problem will be solved by the greater resolution of the WFPC2,
    line_18:       which will enable us to do precise photometry to the required faint
    line_19:       levels in fields where cluster stars outnumber the field stars.
    line_20:       Although our scientific objectives have not been met by our previous
    line_21:       photometry of NGC 6293 and 6352 with the PC, these data have shown
    line_22:       that the project is feasible with the WFPC2.

  question:        9
    section:       1
    line_1:        Our previous HST work consisted of the Cycle 1 proposal, GO 2419,
    line_2:        "The Chronology of the Formation of the Galactic Halo and Disk".
    line_3:        The present  proposal is a continuation of this earlier project which
    line_4:        did receive some telescope time to see if it was feasible with the
    line_5:        impaired HST.  Hence, this proposal has the same title, scientific
    line_6:        objectives, and P.I. and Co-I's as this earlier project.

  question:        10
    section:       1
    line_1:        The computational, image display, and software resources available at
    line_2:        Yale, Boston University, Arizona, North Caroline, Hawaii, Michigan,
    line_3:        Berkeley, and the Anglo-Australian Observatory (AAO) will be used for
    line_4:        the data reduction and analysis.  The ground-based observations that
    line_5:        are necessary to support this project will be made with the telescopes
    line_6:        of Yale, Hawaii, Arizona, and AAO.  The resources of Yale's Center for
    line_7:        Solar and Space Research will be used for the computation of
    line_8:        evolutionary tracks and isochrones.  Graduate students
    line_9:        will take part in the data reduction, the acquisition of the
    line_10:       ground-based observations, and the theoretical computations.
