1  Errors enlarged by us to 4${}\Gamma /\sqrt {\mathit N }$; see the note with the ${{\mathit K}^{*}{(892)}}$ mass.
2  Number of events in peak re-evaluated by us.
3  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.
4  From a partial wave amplitude analysis.
