Notes
-----
The general approach to inference of unknown power spectra is detailed
in [#]_, where the "critical" filter formula used here is derived. The
further incorporation of a smoothness prior is detailed in [#]_, where
the underlying formulas of this implementation are derived and
discussed in terms of their applicability.
