1  From the combined fit of the ${{\mathit \tau}^{-}}$ data from ANDERSON 2000A and SCHAEL 2005C and ${{\mathit e}^{+}}{{\mathit e}^{-}}$ data from the compilation of BARKOV 1985 , AKHMETSHIN 2004 , and ALOISIO 2005 . 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 .
