摘要：

A partial-wave analysis of single-pion photoproduction data has been completed. This study extends from threshold to 2 GeV in the laboratory photon energy, focusing mainly on the influence of new measurements and model dependence in the choice of parametrization employed above the two-pion threshold. Results are used to evaluate sum rules and estimate resonance photodecay amplitudes. These are compared to values obtained in the MAID analysis.
