Notes. The symbol “∼” implies that the respective parameter has a prior as given by the right-hand side distribution; Uni denotes a uniform distribution within the indicated limits; N(μ, σ2) denotes a (normal) Gaussian distribution with the indicated mean and variance; and ai denotes the component amplitude of component i at the given reference frequency ν0, i, and si is spectral energy density, i.e., the observed signal at a given frequency, ν.
