Radial profile centered on EC1, i.e., (RA,Dec) = (6:46:15.8501,0:06:26.197) for module A. The solid horizontal line indicates the surface number density of stars in the B module, taken as the field population surface number density. Objects brighter than F200W = 19.5 were used, to ensure completeness in the central parts of the cluster as outlined above. The best-fit King profile is shown with a core radius of 0.1 pc.
