We suggest that the error quoted in the Mainz determination of the E2/M1 ratio (at the resonance energy) should be enlarged. A term dropped in expressions used by this group could be significant.

We show how the stability of the E2/M1 ratio, evaluated at the T-matrix pole, can be understood given a much wider variation at the K-matrix pole.

We reply to the Comment of A.M. Sandorfi et al. [nucl-th/9707028] on the E2/M1 ratio from the Mainz photoproduction data, nucl-th/9707028 v2. We support our published result for the E2/M1 ratio of REM = -(2.5 +- 0.2 +- 0.2)%.
