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. ! ! end of abstract general_form_proposers: lname: KING fname: IVAN mi: R. inst: UC, BERKELEY country: USA ! lname: RENZINI fname: A. inst: BOLOGNA, UNIVERSITY OF country: ITALY esa: X ! lname: DISNEY fname: MICHAEL mi: J. inst: UNIVERSITY COLLEGE, CARDIFF country: UNITED KINGDOM esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: on 8 M31 globulars: line_2: f/96, F430W, 600 s (par.

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. ! !end of general form text general_form_address: lname: KING fname: IVAN mi: R. title: DR. category: PI inst: UC BERKELEY addr_1: ASTRONOMY DEPT. city: BERKELEY state: CA zip: 94720 country: USA ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: M31-G219 name_2: MIV descr_1: M31 GLOBULAR CLUSTER pos_1: RA=00H40M34.2S+/-.1S, pos_2: DEC=+39D32'48"+/-1" equinox: 1950 ! targnum: 2 name_1: M31HALO-FIELD2 descr_1: M31 HALO FIELD NEAR G219 pos_1: RA=00H40M34.2S+/-.1S, pos_2: DEC=+39D32'48"+/-1", pos_3: REGION, R=394" equinox: 1950 ! ! end of fixed targets !
