The ultraviolet and optical data reveal a population of hot main-sequence (MS) stars with ages of 2-10Myr. We also find populations of blue supergiants with ages between 10 and 40Myr and red supergiants with ages between 10 and 100Myr. Description: The data for this study are a set of UV, optical, and NIR images obtained with the Wide-Field and Planetary Camera 2 (WFPC2) and NICMOS on board HST. We have WFPC2 images taken through the F300W, F606W, and F814W filters, and a NICMOS image taken with the NIC3 camera through the F160W filter.
