Top: Marginal likelihood for models M₁ and M₂ as a function of the period, with uncertainty, computed using Equation (14). Bottom: Bayes factors for the relative plausibility between M₁ and M₂ as a function of the oscillation period, computed using Equation (15). The solid (dotted) line corresponds to the use of uniform (Gaussian) priors. A value of σ_P = 10 min and a 2D grid with N_n = N_B = 800 points were considered.
