1  From ${{\mathit \pi}^{+}}$ ${{\mathit p}}$ $\rightarrow$ ( ${{\mathit \Lambda}}{{\mathit \pi}^{+}}$) ${{\mathit K}^{+}}$ . $\mathit J$ $>{}^{}1/2{}^{}$ is not required by the data.
2  From ${{\mathit \pi}^{+}}$ ${{\mathit p}}$ $\rightarrow$ ( ${{\mathit \Lambda}}{{\mathit \pi}^{+}}$) ( ${{\mathit K}}{{\mathit \pi}}$) ${}^{+}$. $\mathit J$ $>{}^{}1/2{}^{}$ is indicated, but large background precludes a definite conclusion.
3  See the ${{\mathit \Sigma}{(1670)}}$ Listings. AGUILAR-BENITEZ 1970B with three times the data of PRIMER 1968 find no evidence for the ${{\mathit \Sigma}{(1690)}}$.
4  This analysis, which is difficult and requires several assumptions and shows no unambiguous ${{\mathit \Sigma}{(1690)}}$ signal, suggests $\mathit J{}^{P} = 5/2{}^{+}$. Such a state would lead all previously known ${{\mathit Y}^{*}}$ trajectories.
