    "abstract": "We present a combined analysis of the new eta photoproduction data for total\nand differential cross sections, target asymmetry and photon asymmetry. Using\nbasic assumptions, this allows a model-independent extraction of the $E_{2-}$\nand $M_{2-}$ multipoles as well as resonance parameters of the $D_{13}(1520)$\nstate. At higher energy, we show that the photon asymmetry is extremely\nsensitive to small multipoles that are excited by photons in the helicity 3/2\nstate. These could be, e.g., the $F_{15}(1680)$, the $F_{17}(1990)$, or the\n$G_{17}(2190)$ resonances.",
