Note: See the Particle Listings below for the energy limits used in this measurement.
Note: Most of this radiative mode, the low-momentum ${{\mathit \gamma}}$ part, is also included in the parent mode listed without ${{\mathit \gamma}}$'s.
The following data is related to the above value:
$\Gamma({{\mathit K}_S^0}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \gamma}})/\Gamma({{\mathit K}_S^0}$ $\rightarrow$ ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}})$
