1  From a partial-wave analysis of data using a K-matrix formalism with 5 poles.
2  CHABAUD 1981 is a reanalysis of PAWLICKI 1977 data.
3  From an amplitude analysis where the ${{\mathit f}_{{2}}^{\,'}{(1525)}}$ width and elasticity are in complete disagreement with the values obtained from ${{\mathit K}}{{\overline{\mathit K}}}$ channel, making the solution dubious.
4  From a fit to the ${{\mathit D}}$ with ${{\mathit f}_{{2}}{(1270)}}-{{\mathit f}_{{2}}^{\,'}{(1525)}}$ interference. Mass fixed at 1516 MeV.
