1  Uses Dalitz plot analysis of ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{0}}{{\mathit \pi}^{+}}{{\mathit \pi}^{-}}$ decays and the first of two equivalent solutions is used.
2  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.
