1  From a three-resonance fit to the Born cross section in the range $\sqrt {s }$ = $3.808 - 4.951$ GeV. Supersedes ABLIKIM 2020O.
2  From a fit to the cross section for ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}^{+}}{{\mathit D}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ in the range $\sqrt {s }$ = $4.190 - 4.946$ GeV.
3  From a three-resonance fit to the Born cross section in the range $\sqrt {s }$ = $3.7730 - 4.7008$ GeV. Parameters depend on the existence or non-existence of a state near 4.5 GeV.
4  From a three-resonance fit to the Born cross section in the range $\sqrt {s }$ = $4.008 - 4.698$ GeV.
5  From a five-resonance fit to the cross section for ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit J / \psi}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit \gamma}}{{\mathit \ell}^{+}}{{\mathit \ell}^{-}}$.
6  From a two-resonance fit. Supersedes WANG 2007D.
7  From a two-resonance fit.
8  From a fit to the ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \psi}{(3823)}}$ cross section between 4.23 and 4.70 GeV with two coherent Breit-Wigner resonances. The data is also consistent with a single peak with mass $4417.5$ $\pm26.2$ $\pm3.5$ MeV and width $245$ $\pm48$ $\pm13$ MeV.
9  From a fit of the measured cross section in the range $\sqrt {s }$ = $3.808 - 4.600$ GeV.
10  From a three-resonance fit. Superseded by ABLIKIM 2022AM.
11  From a fit to the cross section for ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \psi}{(2S)}}$ $\rightarrow$ 2 ( ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$) ${{\mathit \ell}^{+}}{{\mathit \ell}^{-}}$ obtained from 16 center-of-mass energies between 4.008 and 4.600 GeV and comprising 5.1 fb${}^{-1}$. Superseded by ABLIKIM 2021AJ.
12  From a three-resonance fit.
13  From a combined fit of BELLE, BABAR and BES3 ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit J / \psi}}$ and ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \psi}{(2S)}}$ data.
14  From a combined fit of AUBERT 2007S and WANG 2007D data with two resonances.
15  From a single-resonance fit. Systematic errors not estimated.
