1  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. Value is obtained from ${{\mathit S}}$ = $-0.34$ $\pm0.12$ $\pm0.05$ using ${{\mathit S}}$ = ${{\mathit S}}_{+}$ (1 $−$ 2 ${{\mathit R}}_{\perp}$) with ${{\mathit R}}_{\perp}$ = $0.158$ $\pm0.029$.
2  AUBERT,BE 2005A reports a $\mathit CP$-odd fraction ${{\mathit R}}_{\perp}$ = $0.125$ $\pm0.044$ $\pm0.007$.
