    "abstract": "We compare results for the D13(1520) photon-decay amplitudes determined in\nanalyses of eta- and pion-photoproduction data. The ratio of helicity\namplitudes (A_3/2 / A_1/2), determined from eta-photoproduction data, is quite\ndifferent from that determined in previous analyses of pion-photoproduction\ndata. We consider how strongly the existing pion-photoproduction data constrain\nboth this ratio and the individual photon-decay amplitudes.",
