The data were taken in the filters F555W and F814W using the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope (HST). Photometry was performed using the ACS module of the stellar photometry package DOLPHOT. We detected more than 5500 stars with a magnitude range of 14≲m555≲28mag. Three prominent stellar concentrations are identified with star counts in the observed field, the association NGC 602 itself, and two clusters, one of them not being currently in any known catalog. The color-magnitude diagrams (CMDs) of both clusters show features typical for young open clusters, while that of the association reveals bright main-sequence (MS) and faint pre-main-sequence (PMS) stars as the members of the system. Description: The data used in our analysis are obtained with the Wide Field Channel (WFC) of the ACS within the HST GO Program 10248 on July 14 and July 18 2004. Images are taken in the F555W and F814W filters. A single ACS/WFC pointing covering ∼3.4'x3.4' was centered on NGC 602/LHA 115-N90. At the distance of the SMC this field of view (FOV) corresponds to an extent of ∼57x57pc. File Summary:
