1  From the combined analysis of ANISOVICH 1999C and ANISOVICH 1999F on ${{\overline{\mathit p}}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit \eta}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$, ${{\mathit \pi}^{0}}{{\mathit \pi}^{0}}$, ${{\mathit \eta}}{{\mathit \eta}}$, ${{\mathit \eta}}{{\mathit \eta}^{\,'}}$, ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$.
2  Isospins 0 and 1 not separated.
3  From a fit to the total elastic cross section.
4  Referred to as ${{\mathit U}}$ or ${{\mathit U}}$ region by ALSPECTOR 1973.
