DPWA Isospin-1 total $\sigma{}$
1  MORRIS 1978 obtains an equally good fit without including this resonance.
2  Total cross-section bump with ($\mathit J$+1/2) $\Gamma _{{\mathrm {el}}}$ $/$ $\Gamma _{{\mathrm {total}}}$ is 0.06 seen by CARROLL 1976.
3  Total cross-section bump with ($\mathit J$+1/2) $\Gamma _{{\mathrm {el}}}$ $/$ $\Gamma _{{\mathrm {total}}}$ is 0.04 seen by CARROLL 1976.
