1  From a full four-body amplitude analysis of the ${{\mathit B}^{-}}$ $\rightarrow$ ${{\mathit D}^{*+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{-}}$ decay.
2  From the combined fit of the ${{\mathit M}}({{\mathit D}^{+}}{{\mathit \pi}^{-}}$) and ${{\mathit M}}({{\mathit D}^{*+}}{{\mathit \pi}^{-}}$) distributions. and A$_{{{\mathit D}_{{{2}}}}}$ fixed to the theoretical prediction of $-1$.
3  Fit includes the contribution from ${{\mathit D}_{{{1}}}^{*}{(2430)}^{0}}$.
