\subsection{Systematic Uncertainties} 

The various systematic uncertainties determined in Sec. II, III are listed in
Tables \ref{table:Fpi1_syst_unc_pl},\ref{table:Fpi2_syst_unc_pl}.  
Those items not discussed explicitly in these sections are assumed to be the
same as for the previously published $^1$H analyses.  These systematic
uncertainties are subdivided into correlated and uncorrelated contributions.
The correlated uncertainties, i.e., those that are the same for both $\epsilon$
points, such as target thickness corrections, are attributed directly to the
separated cross sections.  Uncorrelated uncertainties are attributed to the
unseparated cross sections, with the result that in the separation of
$\sigma_L$ and $\sigma_T$ are inflated, just as the statistical uncertainties,
by the factor $1/\Delta\epsilon$ (for $\sigma_L$), which is about three.  The
uncorrelated uncertainties can be further subdivided into those that differ in
size between $\epsilon$ points, but may influence the $t$-dependence at a fixed
value of $\epsilon$ in a correlated way.  The largest contributions to the
``t-correlated'' uncertainty are acceptance, model dependence, and kinematic
offsets, and as a result, they are the dominating systematic uncertainties for,
e.g. $\sigma_L$.

\subsection{Separated Cross Sections} 

The separated cross sections are shown in Fig.~\ref{fig:xsec} and are listed in
Tables~\ref{tab:xsec_pl} , \ref{tab:xsec_mn}.  The $\pi^+$ L,T cross sections
on $^2$H are compared to our previous cross sections on $^1$H in
Fig.~\ref{fig:1h2h}.

\subsection{$\pi^{-}/\pi^{+}$ Separated Response Function Ratios}

Separated cross section $\pi^{-}/\pi^{+}$ ratios are shown in
Fig. \ref{fig:mpratio} for $\sigma_L$ and $\sigma_T$.  L/T Ratios for the
$\pi^+$ and $\pi^-$ reactions are shown in Fig. \ref{fig:ltratio}.
