THE STAR-FORMATION HISTORY IN THE VICINITY OF NGC 1866 IN THE LARGE MAGELLANIC CLOUD

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 inch telescope at Siding Spring Observator. Combining our results with recent 4-meter 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 and increase in the star formation rate ~3 Gyrs 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.
