1  From a partial wave amplitude analysis at $\sqrt {s }$ = 2.125 GeV which includes all the possible intermediate states that match $\mathit J{}^{PC}$ conservation in the subsequent two-body decay. The intermediate states are parameterized with the relativistic Breit-Wigner functions. Statistical error only.
2  From the fit with two resonances.
3  From a fit with two resonances with the JACOB 1972 continuum.
4  Supersedes FRABETTI 2001.
