Notes. For the former, the posterior mean and standard deviation are given in nHz. For the latter, we give the parameters of the three-component Gaussian mixture model used to represent the joint posterior density, as inferred using the EM algorithm. The weights are pk, k = 1, 2, 3. The vector (Ω0/2π, Ω1/2π) is the mean vector of each component (in nHz). The coefficients σi, j, i, j = 1, 2, of the covariance matrices are given in nHz2. We note that σ1, 2 = σ2, 1.
