1  From the combined analysis of ANISOVICH 2000J, ANISOVICH 2001D, ANISOVICH 2001E, and ANISOVICH 2002.
2  From a fit to the total elastic cross section.
3  Isospins 0 and 1 not separated.
4  Seen as bump in $\mathit I = 1$ state. See also COOPER 1968. PEASLEE 1975 confirm ${{\overline{\mathit p}}}{{\mathit p}}$ results of ABRAMS 1970, no narrow structure.
