1  See however KLOET 1996 who fit ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ only and find waves only up to $\mathit J = 3$ to be important but not significantly resonant.
2  $\mathit I(\mathit J{}^{P}) = 1(1{}^{-})$ from simultaneous analysis of ${{\mathit p}}$ ${{\overline{\mathit p}}}$ $\rightarrow$ ${{\mathit \pi}^{-}}{{\mathit \pi}^{+}}$ and ${{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$ .
