1  Statistical significance of 3.5 ${{\mathit \sigma}}$.
2  Statistical error only, with significance of 5.9 $\sigma $ (from a fit with a 19$\%$ CL). Identified as the same structure observed in ABLIKIM 2017V in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \psi}{(2S)}}$ decays.
3  Statistical error only, with significance of 9.2 $\sigma $. From an unbinned maximum likelihood fit of the ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \psi}{(2S)}}$ Dalitz plot from data collected at $\sqrt {s }$ = 4.416 GeV for a $\mathit J{}^{C} = 1{}^{+}$ state. The fit does not match the detailed structure of the data, having a C.L. of only 8$\%$.
