1  Requires 0.8 $<$ $\mathit M_{ {{\mathit K}_S^0} {{\mathit \pi}^{0}} }$ $<$ 1.0 GeV/c${}^{2}$.
2  Assumes $\mathit C$( ${{\mathit B}^{0}}$ $\rightarrow$ ${{\mathit K}^{*}{(892)}^{0}}{{\mathit \gamma}}$ ) = 0.
3  Based on a total signal of $105$ $\pm14$ events with ${{\mathit K}^{*}{(892)}^{0}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit \pi}^{0}}$ only.
