To expand on the recent single WFPC2 field obtained in the vicinity of this cluster, we have measured the luminosity function in a one-third by one-half degree field in the LMC with the 40-in. telescope at Siding Spring Observatory. Combining our results with recent 4-m and WFPC2 observations, we examine the constraints on the star-formation history of the field from 108 to 1010 years ago. The simple model derived from the WFPC2 data with an increase in the star-formation rate ∼3 Gyr ago fits the combined data. However, this rate increase seems to have been unique. This event notwithstanding, the smooth luminosity function from V = 16 to V = 22 suggests steady star formation rather than a star-formation history dominated by intense bursts.
