RPA [@nieves] is implemented into [<span style="font-variant:small-caps;">NEUT</span>]{}as a modification to the 1p1h cross section as a function of [$E_{\nu}$]{}and [$Q^{2}$]{}. Figure \[fig:RPA\_ratio\_NEUT\] shows the ratio of the Nieves 1p1h cross section with RPA included over the bare 1p1h cross section; these two-dimensional tables of the ratio were supplied by the authors of Reference [@nieves] and are used to apply the RPA correction in [<span style="font-variant:small-caps;">NEUT</span>]{}. The Nieves RPA calculation uses the [*local*]{} Fermi gas nuclear model, and [<span style="font-variant:small-caps;">NEUT</span>]{}only has a [*global*]{} Fermi gas model implemented for 1p1h interactions, but the authors of the RPA calculation have noted [@nievesExtension] that the same ratio can be applied, with reasonable precision, to a global Fermi gas. Because of the model dependence, the same ratios cannot be applied to modify the 1p1h interactions calculated with a SF model, and no RPA calculation performed in the context of SF nuclear model is available. Two different RPA calculations are available from the same authors, termed relativistic and non-relativistic, which affect
