Before revision:  The two methods provide similar general pictures , however, the posterior distributions of the Bayesian approach contain richer information . Conclusions: The Bayesian method described in this paper represents a reliable approach for localization of multiple dipoles in the frequency domain.
After revision:  The two methods provide similar general pictures , however, the posterior distributions of the Bayesian approach contain much richer information at the price of a higher computational cost . Conclusions: The Bayesian method described in this paper represents a reliable approach for localization of multiple dipoles in the frequency domain.
