1  Assuming one single Breit-Wigner resonance in ${{\mathit \omega}}{{\mathit \chi}_{{{c2}}}{(1P)}}$ (${{\mathit \chi}_{{{c2}}}}$ $\rightarrow$ ${{\mathit \gamma}}{{\mathit J / \psi}}$). Measured ${\Gamma}_{\mathrm {{\mathit e}} {{\mathit e}}}\cdot{}B({{\mathit \omega}}{{\mathit \chi}_{{{c1}}}{(1P)}}$) = $1.86$ $\pm0.32$ $\pm0.13$ eV.
2  From a cross-section measurement of ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}^{*0}}{{\mathit D}^{*-}}{{\mathit \pi}^{+}}$ between 4.189 and 4.951 GeV, assuming a coherent sum of 3 Breit-Wigner resonances plus a continuum amplitude. $\Gamma ({{\mathit e}^{+}}{{\mathit e}^{-}})\cdot{}B({{\mathit D}^{*0}}{{\mathit D}^{*-}}{{\mathit \pi}^{+}}$) = $107 - 1744$ eV depending on solutions I $-$ VIII with the same fit qualities. The two other resonances have masses (widths) $4209.6$ $\pm7.5$ ($81.6$ $\pm19.9$) MeV and $4675.3$ $\pm29.7$ ($218.3$ $\pm73.5$) MeV.
