NGC line_2: 6397 has the smallest distance modulus (12.3) among globular clusters. We will line_3: have a significant color-magnitude array down almost to V absolute magnitude line_4: 14, including both red dwarfs and white dwarfs. Exposures will be made at the line_5: center and at two other points, in order to get overall luminosity functions, line_6: for which the radial distribution must be known. line_8: Simultaneous exposures with the WFC will be concentrated on a single outer line_9: field, to go to a deep limiting magnitude. ! ! end of abstract general_form_proposers: lname: KING fname: IVAN mi: R. inst: UC, BERKELEY country: USA ! lname: CASTELLANI fname: V. inst: ROME, UNIVERSITY OF country: ITALY esa: X ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: on each of 3 fields in NGC 6397: line_2: f/96, F480LP, 3000s (par.
