abstract:

    line_1:        Since all of the globular clusters in M31 are at the same distance modulus,
    line_2:        they offer an unparalleled opportunity to compare absolute magnitudes of
    line_3:        various features of their HR diagrams, especially the horizontal branch.
    line_4:        Clusters will be studied in B and V, with 0.1 mag accuracy in each color at 1
    line_5:        mag below the HB. The clusters chosen cover a range in meallicity and hopefully
    line_6:        a range in the second parameter too.
    line_7:        A number of clusters will get preliminary shorter exposures, to delineate the
    line_8:        HB morphology; then the best 3 will be chosen for full study.
    line_9:        Parallel WFC exposures will be made on fields of the M31 halo. These will
    line_10:       delineate the density distribution and the upper part of the luminosity
    line_11:       function (including HB morphology).
    line_12:       Parallel PC exposures in King GTO programs will add to the sample of M31
    line_13:       globulars.

  question:        3
    section:       1
    line_1:        on 8 M31 globulars:
    line_2:        f/96, F430W, 600 s (par. WFC, F555W)
    line_3:        f/96, F480lp, 900 s (par. WFC, F785LP)
    line_4:        then on the 3 determined to be most favorable:
    line_5:        same setup, but exp. 3600s and 2900 s, resp.
    line_7:        Cycle 1: none
    line_8:        Cycle 2: exp. 9-17
    line_9:        Cycle 3: exp. 18, 19

  question:        4
    section:       1
    line_1:        resolving power

!

  question:        7
    section:       1
    line_1:        To be done at Rome Obs. by Buonanno & Corsi. They have excellent software for
    line_2:        reduction of digital frames of star fields.

!

  question:        8
    section:       1
    line_1:        Roll angles may be chosen by operations, but must remain the same for all
    line_2:        exposures on each target.

  question:        10
    section:       1
    line_1:        Berkeley: personnel, travel funds
    line_2:        Bologna: personnel, offices
    line_3:        Rome: computer, software, personnel

  question:        12
    section:       1
    line_1:        Program will be considerably expanded by PC exposures taken in parallel with
    line_2:        King programs on imaging of galaxies in M31 group and spectroscopy of M31/M32.
    line_4:        GTO time to be charged 91.4% FOC IDT and 8.6% King.

!

  question:        13
    section:       1
    line_1:        Study of HB morphology and RGB shape and color for 14 globular clusters in
    line_2:        M31--9 of them to the HB level and 5 more a magnitude deeper. This should
    line_3:        determine the dependence of HB absolute magnitude on HR-diagram morphology.
    line_4:        Parallel exposures will get color-magnitude arrays at many points in the M31
    line_5:        halo, and the density distribution in the halo.
