1  Uses quantum correlations in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\overline{\mathit D}}^{0}}$ at the ${{\mathit \psi}{(3770)}}$, where the decay rates of $\mathit CP$-tagged ${{\mathit K}^{-}}{{\mathit \pi}^{-}}$2 ${{\mathit \pi}^{+}}$ final states depend on $\mathit R_{{{\mathit K}}3 {{\mathit \pi}}}$ and $\delta {}^{{{\mathit K}}3 {{\mathit \pi}}}$.
2  A combined fit with a recent LHCb ${{\mathit D}^{0}}{{\overline{\mathit D}}^{0}}$ mixing results in AAIJ 2016F is also reported to be ($128$ ${}^{+28}_{-17})^\circ{}$.
3  Obtained by analyzing CLEO-c data but not authored by the CLEO Collaboration.
4  LOWREY 2009 uses quantum correlations in ${{\mathit e}^{+}}$ ${{\mathit e}^{-}}$ $\rightarrow$ ${{\mathit D}^{0}}{{\overline{\mathit D}}^{0}}$ at the ${{\mathit \psi}{(3770)}}$, where the decay rates of $\mathit CP$-tagged ${{\mathit K}^{-}}{{\mathit \pi}^{-}}$2 ${{\mathit \pi}^{+}}$ final states depend on $\mathit R_{{{\mathit K}}3 {{\mathit \pi}}}$ and $\delta {}^{{{\mathit K}}3 {{\mathit \pi}}}$. A fit that includes external measurements of charm mixing parameters gets $\delta {}^{{{\mathit K}}3 {{\mathit \pi}}}$ = ($114$ ${}^{+26}_{-23})^\circ{}$.
