The data will be line_4: used to determine the luminosity function in the line_5: centers of these clusters where stellar crowding is line_6: too large for ground-based stellar photometry. The line_7: luminosity function will be compared with those of line_8: R136, a much denser and more extreme young cluster, line_9: and clusters in the different galactic environments line_10: of our Galaxy and M31. The background fields will line_11: be used to subtract the non-cluster population line_12: and to examine the disk population of the LMC. ! ! 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 line_2: F814W on cluster and line_3: background fields in the LMC. ! question: 6 section: 1 line_1: The objects should be placed in WF3. ! question: 13 section: 1 line_1: HR diagrams are planned in filters F555W and F814W for line_2: two star clusters and background fields in the Large line_3: Magellanic Clouds.
