1  Includes data of ETKIN 1985.
2  From a Breit-Wigner fit involving 9 resonances and a resonating exotic ${{\mathit \eta}_{{{1}}}{(1855)}}$ $\rightarrow$ ${{\mathit \eta}}{{\mathit \eta}^{\,'}}{\mathit P}{\mathrm -wave}$.
3  From a four pole K-matrix reanalysis of ETKIN 1988 and BARBERIS 2000C data
4  Statistically very weak, only $1.4$ s.d.
