The whole of this program is to be executed in Cycle 2 or thereafter. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The FOC is the only instrument having uvby photometry which is essential for this project. Also, the highest possible angular resolution is of importance in order to avoid crowding problems in the LMC bar. ------------------------------------------------------------------------------------ 13. The age-metallicity relation and luminosity function in the central bar of the LMC will be determined through deep FOC exposures in the four Stromgren uvby passbands. ------------------------------------------------------------------------------------ 11.
