RVUE
1  From a partial wave analysis of the systems (${{\mathit \gamma}}{{\mathit X}}$), with ${{\mathit X}}$ $\rightarrow$ ${{\mathit \eta}^{\,'}}{{\mathit \eta}^{\,'}}$, and (${{\mathit \eta}^{\,'}}{{\mathit X}}$), with ${{\mathit X}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \eta}^{\,'}}$ in the decay ${{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \eta}^{\,'}}{{\mathit \eta}^{\,'}}$. The intermediate resonance ${{\mathit X}}$ is parametrized by a constant-width, relativistic Breit-Wigner.
2  From partial wave analysis including all possible combinations of 0${}^{++}$, 2${}^{++}$, and 4${}^{++}$ resonances.
3  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 $37$ $\pm19$, $4$ ${}^{+12}_{-4}$, and $59$ ${}^{+21}_{-19}$, respectively.
4  Statistical error only.
5  From a four pole K-matrix reanalysis of ETKIN 1988 and BARBERIS 2000C data.
