From left to right, the 5  ×  5 pc (20″    ×    20″) images of the simulated MASSCLEAN clusters of 420, 1000, and 4000 M_⊙. The images were made of simulated clusters, with HST ACS resolution, at the distance of the LMC in the V-band. The green diamonds mark the brightest/most massive star in the cluster. The red circles indicate stars that would have been detected on the actual images (see Fig. 3). In all cases, the underlying cluster would have been detected.
