1  Width errors enlarged by us to 4${}\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
2  Uses same data as HYAMS 1975 and BECKER 1979 .
3  From a phase shift solution containing a ${{\mathit f}_{{2}}^{\,'}{(1525)}}$ width two times larger than the ${{\mathit K}}{{\overline{\mathit K}}}$ result.
4  From phase-shift analysis. Error takes account of spread of different phase-shift solutions.
