Before revision:  The procedure is based on the comparison of the radial distribution function , g(r), from experiments and Brownian dynamic (BD) simulations . The domains were modeled as disks with surface dipolar density, whose strength was varied to best describe the experimentally determined monolayer structure. For comparison, the point dipole approximation was also studied.
After revision:  The procedure is based on the comparison of the pair correlation function obtained from experiments with that obtained from Brownian dynamics simulations of a model system.
