1  Uses Dalitz plot analysis of the ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ final state decays.
2  Uses Dalitz plot analysis of ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ decays.
3  Uses Dalitz plot analysis of ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays.
4  The first of two equivalent solutions is used.
5  Uses Dalitz plot analysis of ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays and the first of two consistent solutions that may be preferred.
6  Corresponds to 90$\%$ confidence range $-0.31<\mathit A_{\mathit CP}<0.78$.
