1  Assumes both $\mathit CP$-even and $\mathit CP$-odd states having the $\mathit CP$ asymmetry.
2  Belle Collab. quotes $\mathit A_{{{\mathit D}^{*+}} {{\mathit D}^{*-}}}$ which is equal to $−\mathit C_{{{\mathit D}^{*+}} {{\mathit D}^{*-}}}$.
3  Measured partially reconstructed candidates when one ${{\mathit D}^{0}}$ meson is not excplicitely reconstructed. Analysis does not separate $\mathit CP$-even and $\mathit CP$-odd component.
4  AUBERT 2003Q reports $\vert \lambda \vert =0.75$ $\pm0.19$ $\pm0.02$ and Im($\lambda )=0.05$ $\pm0.29$ $\pm0.10$. We convert them to $\mathit S$ and $\mathit C$ parameters taking into account correlations.
