N(1860) 5/2+I (J P ) = 21 ( 25 + ) Status:∗∗OMITTED FROM SUMMARY TABLE

Before the 2012 Review, all the evidence for a J P = 5/2+ state witha mass above 1800 MeV was filed under a two-star N(2000). Thereis now some evidence from ANISOVICH 12A for two 5/2+ statesin this region, so we have split the older data (according to mass)
between two two-star 5/2+ states, an N(1860) and an N(2000).
