1  Average of KOZYREV 2016 and KOZYREV 2018 values taking into account the correlated uncertainties. Supersedes individual KOZYREV 2016 and KOZYREV 2018 results.
2  Using a vector meson dominance model with contribution from ${{\mathit \phi}{(1020)}}$ and higher mass excitations of ${{\mathit \rho}{(770)}}$, ${{\mathit \omega}{(782)}}$, and ${{\mathit \phi}{(1020)}}$.
3  Using a phenomenological model based on KUHN 1990 with a sum of Breit-Wigner resonances for ${{\mathit \rho}{(770)}}$, ${{\mathit \omega}{(782)}}$, ${{\mathit \phi}{(1020)}}$ and their higher mass excitations.
4  Update of AKHMETSHIN 1999D
5  From the combined fit assuming that the total ${{\mathit \phi}{(1020)}}$ production cross section is saturated by those of ${{\mathit K}^{+}}{{\mathit K}^{-}}$ , ${{\mathit K}_{{S}}}{{\mathit K}_{{L}}}$ , ${{\mathit \pi}^{+}}{{\mathit \pi}^{-}}{{\mathit \pi}^{0}}$ , and ${{\mathit \eta}}{{\mathit \gamma}}$ decays modes and using ACHASOV 2000B for the ${{\mathit \eta}}{{\mathit \gamma}}$ decay mode.
6  Width errors enlarged by us to 4${}\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
7  Strongly correlated with AKHMETSHIN 2004 .
8  Systematic errors not evaluated.
