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.
