1  The Breit-Wigner parameters from a fit with seven intermediate resonances. The S-matrix pole position is ($764$ $\pm63$ ${}^{+71}_{-54}$) $−$ ${\mit i}$ ($306$ $\pm149$ ${}^{+143}_{-85}$) MeV.
2  From a fit including ten additional resonances and energy-independent Breit-Wigner width.
3  A fit in the ${{\mathit K}_{{0}}^{*}{(700)}}$ + ${{\mathit K}^{*}{(892)}}$ + ${{\mathit K}^{*}{(1410)}}$ model with mass and width of the ${{\mathit K}_{{0}}^{*}{(700)}}$ from ABLIKIM 2006C well describes the left slope of the ${{\mathit K}_S^0}$ ${{\mathit \pi}^{-}}$ invariant mass spectrum in ${{\mathit \tau}^{-}}$ $\rightarrow$ ${{\mathit K}_S^0}$ ${{\mathit \pi}^{-}}{{\mathit \nu}_{{\tau}}}$ decay studied by EPIFANOV 2007 . Averaged value from different parameterizations.
4  Not seen by KOPP 2001 using 7070 events of ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \pi}^{0}}$ . LINK 2002E and LINK 2005I show clear evidence for a constant non-resonant scalar amplitude rather than ${{\mathit K}_{{0}}^{*}{(700)}}$ in their high statistics analysis of ${{\mathit D}^{+}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit \pi}^{+}}{{\mathit \mu}^{+}}{{\mathit \nu}_{{\mu}}}$ .
5  AUBERT 2007T does not find evidence for the charged ${{\mathit K}_{{0}}^{*}{(700)}}$ using 11k events of ${{\mathit D}^{0}}$ $\rightarrow$ ${{\mathit K}^{-}}{{\mathit K}^{+}}{{\mathit \pi}^{0}}$ .
6  Using parameters from the model that fits data best.
7  A Breit-Wigner mass and width.
8  Breit-Wigner parameters. A significant ${\mathit S}{\mathrm -wave}$ can be also modeled as a non-resonant contribution.
9  Reanalysis of ASTON 1988 using interfering Breit-Wigner amplitudes.
