The reaction γ+p→K++Σ+π was used to determine the invariant mass distributions or “line shapes” of the Σ+π−, Σ−π+, and Σ0π0 final states, from threshold at 1328 MeV/c2 through the mass range of the Λ(1405) and the Λ(1520). The measurements were made with the CLAS system at Jefferson Lab using tagged real photons, for center-of-mass energies 1.95
