1  Applies the Unitary $\&$ Analytic Model of the pion electromagnetic form factor of DUBNICKA 2010 to analyze the data of LEES 2012G and ABLIKIM 2016C.
2  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, and AMBROSINO 2011A.
3  Applies the Unitary $\&$ Analytic Model of the pion electromagnetic form factor of DUBNICKA 2010 to analyze the data of FUJIKAWA 2008 .
4  From a Dalitz plot analysis in an isobar model with ${{\mathit \rho}{(1450)}}$ and ${{\mathit \rho}{(1700)}}$ masses and widths floating.
5  Using the KUHN 1990 parametrization of the pion form factor, neglecting ${{\mathit \rho}}−{{\mathit \omega}}$ interference.
6  Using the GOUNARIS 1968 parametrization of the pion form factor leaving the masses and widths of the ${{\mathit \rho}{(1450)}}$, ${{\mathit \rho}{(1700)}}$, and ${{\mathit \rho}{(2150)}}$ resonances as free parameters of the fit.
7  From the GOUNARIS 1968 parametrization of the pion form factor.
8  $\vert \mathit F_{{{\mathit \pi}}}(0)\vert ^2$ fixed to 1.
9  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 . ${{\mathit \rho}{(1700)}}$ mass and width fixed at 1713 MeV and 235 MeV, respectively. Supersedes BARATE 1997M.
