1  Taking also into account the ${{\mathit K}^{*}_{\mathrm 0}{(1430)}^{0}}$ and ${{\mathit K}^{*}_{\mathrm 2}{(1430)}^{0}}$.
2  Taking into account the ${{\mathit K}^{*}{(892)}^{0}}$, ${\mathit S}{\mathrm -wave}$ and ${\mathit P}{\mathrm -wave}$ (${{\mathit K}^{*}{(1410)}^{0}}$).
3  From the isobar model with a complex pole for the ${{\mathit \kappa}}$.
4  Fit to ${{\mathit K}}{{\mathit \pi}}$ mass spectrum includes a non-resonant scalar component.
5  Inclusive reaction. Complicated background and phase-space effects.
6  Width errors enlarged by us to 4${\times }\Gamma /\sqrt {\mathit N }$; see note.
7  Number of events in peak reevaluated by us.
8  For transverse momenta between 0.6 and 0.8 GeV/c and rapidity 0 $<$ y $<$ 0.5.
9  From a Dalitz plot analysis in an isobar model with charged and neutral ${{\mathit K}^{*}{(892)}}$ masses and widths floating.
10  This value comes from a fit with $\chi {}^{2}$ of 178/117.
11  Systematic uncertainties not estimated.
