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  $\vert \mathit F_{{{\mathit \pi}}}(0)\vert ^2$ fixed to 1.
8  From the GOUNARIS 1968 parametrization of the pion form factor.
9  T-matrix pole.
10  From phase shift analysis of HYAMS 1973 data.
11  Simple relativistic Breit-Wigner fit with constant width.
12  An additional 40 MeV uncertainty in both the mass and width is present due to the choice of the background shape.
13  Included in BECKER 1979 analysis.
