1  Measured in ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{\mp}}{{\mathit K}^{\pm}}$ decays, constraining $-2{{\mathit \beta}_{{{s}}}}$ by the measurement of ${{\mathit \phi}_{{{s}}}}$ = $-0.031$ $\pm0.018$ rad. The value is modulo 180$^\circ{}$.
2  Combines the result with that of AAIJ 2018U, for which the values of the nuisance parameters ${{\mathit \Delta}}{{\mathit m}_{{{s}}}}$, ${{\mathit \Gamma}_{{{s}}}}$ and ${{\mathit \Delta}}{{\mathit \Gamma}_{{{s}}}}$ have been re-evaluated and the related systematic uncertainties updated.
3  Measured in ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{\mp}}{{\mathit K}^{\pm}}$ decays, constraining $-2{{\mathit \beta}_{{{s}}}}$ by the measurement of ${{\mathit \phi}_{{{s}}}}$ = $0.030$ $\pm0.033$ from HFLAV. The value is modulo 180$^\circ{}$.
4  Measured in ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{\mp}}{{\mathit K}^{\pm}}$ decays, constraining $-2{{\mathit \beta}_{{{s}}}}$ by the measurement of ${{\mathit \phi}_{{{s}}}}$ = $0.01$ $\pm0.07$ $\pm0.0$ from AAIJ 2013AR. The value is modulo 180$^\circ{}$ at 68$\%$ CL.
