 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 ${{\mathit D}_{{s}^{(*)-}}}$ .
