1  AAIJ 2017AN value was measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{(*)-}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$ decays relative to ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit D}^{(*)-}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}$ decays.
2  Measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{{\mu}}}}{{\mathit X}}$ decays.
3  Measured using the ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \pi}^{+}}$ decays.
4  Measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}^{+}}{{\mathit D}_{{{s}}}^{-}}$.
5  Measured using ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit K}^{-}}$ decays.
6  AALTONEN 2011AP combines the fully reconstrcuted ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \pi}^{+}}$ decays and partially reconstructed ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}}{{\mathit X}}$ decays.
7  Uses ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}$, and ${{\mathit \phi}}{{\mathit \ell}^{+}}$ vertices.
8  Measured using ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}$ vertices.
9  Measured using ${{\mathit D}_{{{s}}}^{-}}{{\mathit \mu}^{+}}$ vertices.
