1  Utilized the beam constrained invariant mass peak positions for ${{\mathit B}^{*}}$ and ${{\mathit B}_{{{s}}}^{*}}$ to extract the measurement.
2  LEE-FRANZINI 1990 measure $46.7$ $\pm0.4$ $\pm0.2$ MeV for an admixture of ${{\mathit B}^{0}}$, ${{\mathit B}^{+}}$, and ${{\mathit B}_{{{s}}}}$. They use the shape of the photon line to separate the above value for ${{\mathit B}_{{{s}}}}$.
3  Uses 14 candidates consistent with ${{\mathit B}_{{{s}}}}$ decays into final states with a ${{\mathit J / \psi}}$ and a ${{\mathit D}_{{{s}}^{(*)-}}}$.
