This module implements a very simple phenomenological model for the suppression of the
non-linear power spectrum.

:math:`P_m(k, z) = P_m^L(k, z) + A_{mod} [P_m^{NL}(k, z) - P_m^L(k, z)]`

To match the model used in Amon & Efstathiou (2022), the non-linear power spectrum should
be computed using HMCode2020 without baryonic feedback.
