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