1  The observed structure can be due to both the ${{\mathit \phi}{(2170)}}$ and ${{\mathit \rho}{(2150)}}$.
2  Fit includes interference with the ${{\mathit \phi}{(1680)}}$.
3  From the ${{\mathit \phi}}{{\mathit f}_{{0}}{(980)}}$ component.
4  From a fit with two incoherent Breit-Wigners.
5  From the ${{\mathit K}^{+}}{{\mathit K}^{-}}{{\mathit f}_{{0}}{(980)}}$ component.
6  Superseded by LEES 2012F.
