Abstract
We have updated our multipole analyses to incorporate new data from th e low-energy and Delta resonance regions. We note a slight decrease in our estimate of the Delta photodecay amplitudes. This agrees with res ults found in Compton scattering. Our values are also in good agreemen t with another previous determination. We have reexamined our determin ations of the E2/M1 ratio at the resonance energy and at the pole. We find an E2/M1 ratio (at the pole) which is in go od agreement with the recent Mainz value.
