1  Uses fully reconstructed ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{\pm}}{{\mathit \pi}^{\mp}}$ decays.
2  Combines the results from fully reconstructed and partially reconstructed ${{\mathit D}}{{\mathit \pi}}$ events by taking weighted averages. Assumes that systematic errors from physics parameters and fit biases in the two measurements are 100$\%$ correlated.
