1  Belle Collab. quotes $\mathit A_{{{\mathit D}^{*+}} {{\mathit D}^{*-}}}$ which is equal to $−\mathit C_{{{\mathit D}^{*+}} {{\mathit D}^{*-}}}$.
2  Measured partially reconstructed candidates when one ${{\mathit D}^{0}}$ meson is not excplicitely reconstructed. Extracted under assumption of equal ${{\mathit C}}_{+}$ and ${{\mathit C}}_{-}$.
3  AUBERT,BE 2005A reports a $\mathit CP$-odd fraction R$_{\perp}$ = $0.125$ $\pm0.044$ $\pm0.007$.
