1  From partial wave analysis including all possible combinations of 0${}^{++}$, 2${}^{++}$, and 4${}^{++}$ resonances.
2  Breit-Wigner mass. Could also be the $f_2(1910)$.
3  Seen in only one solution.
4  Error increased by spread of two solutions. Included in LONGACRE 1986 global analysis.
5  From a partial-wave analysis of data using a K-matrix formalism with 5 poles. Includes compilation of several other experiments.
6  From an amplitude analysis of the reaction ${{\mathit \pi}^{+}}$ ${{\mathit \pi}^{-}}$ $\rightarrow$ 2 ${{\mathit \pi}^{0}}$ . The resonance in the 2${{\mathit \pi}^{0}}$ final state is not confirmed by PROKOSHKIN 1997 .
