2  These papers report $\mathit E_{{{\mathit \gamma}}}$ in the ${{\mathit B}^{*}}$ center of mass. The ${\mathit m}_{{{\mathit B}^{*}}}–{\mathit m}_{{{\mathit B}}}$ is $0.2$ MeV higher. $\mathit E_{{\mathrm {cm}}}$ = $10.61 - 10.7$ GeV. Admixture of ${{\mathit B}^{0}}$ and ${{\mathit B}^{+}}$ mesons, but not ${{\mathit B}_{{{s}}}}$.
3  LEE-FRANZINI 1990 value is for an admixture of ${{\mathit B}^{0}}$ and ${{\mathit B}^{+}}$. They measure $46.7$ $\pm0.4$ $\pm0.2$ MeV for an admixture of ${{\mathit B}^{0}}$, ${{\mathit B}^{+}}$, and ${{\mathit B}_{{{s}}}}$, and use the shape of the photon line to separate the above value.
4  HAN 1985 is for $\mathit E_{{\mathrm {cm}}}$ = $10.6 - 11.2$ GeV, giving an admixture of ${{\mathit B}^{0}}$, ${{\mathit B}^{+}}$, and ${{\mathit B}_{{{s}}}}$.
