The proposed clusters span a range of age and metallicity, and the line_4: background fields are located at a variety of radial distances within the line_5: galaxies. The data will be used to study cluster ages, the history of star line_6: formation for field stars, the cluster and field luminosity functions, and line_7: distance moduli based on main-sequence fitting. Tidal radii of clusters and line_8: the stellar mass-to-light ratios of cluster and field populations will also be line_9: estimated. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES title: PROF. mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Exposures are planned in each of filters F336W,F555W and F785LP on cluster and line_2: background fields in both Clouds. ! question: 6 section: 1 line_1: Limiting noise is readout noise; exposures cannot be interrupted. ! question: 13 section: 1 line_1: HR diagrams are planned in filters F555W and F785LP for several star clusters line_2: and background fields in the Large and Small Magellanic Clouds.
