Supersedes BARATE 1997M. 2  Assuming ${\mathit m}_{{{\mathit \rho}^{+}}}$ = ${\mathit m}_{{{\mathit \rho}^{-}}}$, $\Gamma _{{{\mathit \rho}^{+}}}$ = $\Gamma _{{{\mathit \rho}^{-}}}$. 3  Applies the Unitary $\&$ Analytic Model of the pion electromagnetic form factor of DUBNICKA 2010 to analyze the data of ACHASOV 2006, AKHMETSHIN 2007, AUBERT 2009AS, AMBROSINO 2011A, and FUJIKAWA 2008.
