1  From energy-independent partial-wave analysis.
2  From a fit to $\mathit Y{}^{2}_{6}$ moment. $\mathit J{}^{P} = 3{}^{-}$ found.
3  From a partial wave amplitude analysis.
4  From a fit to $\mathit Y{}^{0}_{6}$ moment.
5  Errors enlarged by us to 4${}\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
6  ESTABROOKS 1978 find that BRANDENBURG 1976D data are consistent with 175 MeV width. Not averaged.
