1  The coupled-channel analysis of both the ${{\mathit \eta}}{{\mathit \pi}}$ and ${{\mathit \eta}^{\,'}}{{\mathit \pi}}$ systems using ADOLPH 2015 data. The width is extracted from the T-matrix pole.
2  Statistical error negligible.
3  May be a different state: natural and unnatural parity exchanges.
4  Natural parity exchange.
5  Superseded by AGHASYAN 2018B.
6  Superseded by DZIERBA 2006 excluding this state in a more refined PWA analysis, with 2.6 M events of ${{\mathit \pi}^{-}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit \pi}^{-}}{{\mathit \pi}^{-}}{{\mathit \pi}^{+}}{{\mathit p}}$ and 3 M events of ${{\mathit \pi}^{-}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit \pi}^{-}}{{\mathit \pi}^{0}}{{\mathit \pi}^{0}}{{\mathit p}}$ of E852 data.
