Description & Method
-----------------------

The discussion here follows roughly the discussions given by 
`de Angelis et al 2011 <https://ui.adsabs.harvard.edu/abs/2011PhRvD..84j5030D/abstract>`_
and `Marsh et al 2017 <https://ui.adsabs.harvard.edu/abs/2017JCAP...12..036M/abstract>`_. The method
in the code most closely follows the former, but notation often matches the latter.
