RVUE ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}}{{\overline{\mathit D}}}$, hadrons
1  Taking into account interference between the resonant and non-resonant ${{\mathit D}}{{\overline{\mathit D}}}$ production.
2  Reanalysis of data presented in BAI 2002C. From a global fit over the center-of-mass energy region $3.7 - 5.0$ GeV covering the ${{\mathit \psi}{(3770)}}$, ${{\mathit \psi}{(4040)}}$, ${{\mathit \psi}{(4160)}}$, and ${{\mathit \psi}{(4415)}}$ resonances. Phase angle fixed in the fit to $\delta $ = 0$^\circ{}$.
3  Interference between the resonant and non-resonant ${{\mathit D}}{{\overline{\mathit D}}}$ production not taken into account.
4  From the joint analysis of the data on the ${{\mathit D}}{{\overline{\mathit D}}}$ and inclusive hadronic cross sections in the ${{\mathit \psi}{(3770)}}$ region from BaBar, Belle, BES-II, CLEO and KEDR.
