The masses inside the square brackets were measured for each candidate event. The result assumes $\mathit P$ = $−(-1){}^{J}$, (${\mathit m}_{{{\mathit B}^{*+}}}–{\mathit m}_{{{\mathit B}^{+}}}$) = $45.01$ $\pm0.30$ $\pm0.23$ MeV, and uses three relativistic Breit-Wigner functions in the fit for mass difference.
