We consider the impact of two recent π − p → ηn measurements on the ηN scattering length and ηN branching fractions for the N (1535) and N (1520) resonances within a coupled-channel analysis of πN elastic scattering and ηN production data. The sensitivity of these results to model input is also explored.
