Complicated background and phase-space effects. 2  Mass errors enlarged by us to $\Gamma /\sqrt {\mathit N }$. See note. 3  Number of events in peak reevaluated by us. 4  From a Dalitz plot analysis in an isobar model with charged and neutral ${{\mathit K}^{*}{(892)}}$ masses and widths floating. 5  Average of fit results with different parametrizations for the ${{\mathit K}}{{\mathit \pi}}{\mathit S}{\mathrm -wave}$. 6  K-matrix pole. 7  From a partial wave amplitude analysis.
