1  Requires 0.6 $<$ $\mathit M_{{{\mathit K}_S^0} {{\mathit \pi}^{0}}}$ $<$ 0.8 GeV/c${}^{2}$ or 1.0 $<$ $\mathit M_{{{\mathit K}_S^0} {{\mathit \pi}^{0}}}$ $<$ 1.8 GeV/c${}^{2}$.
2  Requires 1.1 $<$ $\mathit M_{{{\mathit K}_S^0} {{\mathit \pi}^{0}}}$ $<$ 1.8 GeV/c${}^{2}$.
3  Requires $\mathit M_{{{\mathit K}_S^0} {{\mathit \pi}^{0}}}$ $<$ 1.8 GeV/c${}^{2}$.
4  Reports $\mathit A_{{{\mathit K}_S^0} {{\mathit \pi}^{0}} {{\mathit \gamma}}}$, which is $−\mathit C_{{{\mathit K}_S^0} {{\mathit \pi}^{0}} {{\mathit \gamma}}}$.
