A, Generative model for simulations to investigate the influence of the hidden source (H) and two measurable sources (A and B). Locations of A and B were varied randomly. B, Results of Monte Carlo simulations testing two model families: with and without a deep (hidden) source (H). Monte Carlo simulations demonstrated that independent of the location and the distance between the visible sources, the model posterior probability provides stable information whether or not inclusion of a hidden source constitutes a better model.
