Pion electromagnetic form factor and charge radius
==================================================

Monopole analysis of the $Q^2$ dependence of the form factor
------------------------------------------------------------

\

Figure \[fig:PQ2Mono\] shows the momentum transfer dependence of our data for the pion form factor at all simulated pion masses. The data set I and II are consistent with each other within the estimated errors. The experimental pion form factor is phenomenologically reasonably described by a monopole form suggested by the vector meson dominance model, $$G_\pi(Q^2) = \frac{1}{1+{Q^2/M^2_{mono}}}.
\label{eq:Mono}$$ Our data are accordant with
