1  Includes data of ETKIN 1985. The percentage of the resonance going into ${{\mathit \phi}}{{\mathit \phi}}{}^{}2{}^{++}$ $\mathit S_{2}$, $\mathit D_{2}$, and $\mathit D_{0}$ is $98$ ${}^{+1}_{-3}$, $0$ ${}^{+1}_{-0}$, and $2$ ${}^{+2}_{-1}$, respectively.
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  Statistically very weak, only $1.4$ s.d.
