 DM2 ${{\mathit J / \psi}}$ $\rightarrow$ 4 ${{\mathit \pi}}{{\mathit \gamma}}$
1  From a single-resonance fit.
2  From a partial wave analysis including ${{\mathit \eta}{(1760)}}$, ${{\mathit f}_{{{0}}}{(1710)}}$, ${{\mathit f}_{{{2}}}{(1640)}}$, and ${{\mathit f}_{{{2}}}{(1910)}}$.
3  From a two-resonance fit.
4  Estimated by us from various fits. Systematic uncertainties not estimated.
