${{\boldsymbol N}{(2000)}}$ $I(J^P)$ = $1/2(5/2^{+})$

Before the 2012 $\mathit Review$, all the evidence for a $\mathit J{}^{P} = 5/2{}^{+}$ state with a mass above 1800 MeV was filed under a two-star ${{\mathit N}{(2000)}}$. There is now some evidence from ANISOVICH 2012A for two ${}^{}5/2{}^{+}$ states in this region, so we have split the older data (according to mass) between two two-star ${}^{}5/2{}^{+}$ states, an ${{\mathit N}{(1860)}}$ and an ${{\mathit N}{(2000)}}$.
