  Data on the reaction $\gamma p\to \omega p$ with $\omega\to\pi^0\gamma$,
taken with unpolarized or polarized beams in combination with an unpolarized or
polarized proton-target, were analyzed within the Bonn-Gatchina (BnGa) partial
wave analysis. Differential cross sections, several spin density matrix
elements, the beam asymmetry $\Sigma$, the normalized helicity difference $E$,
and the correlation $G$ between linear photon and longitudinal target
polarization were included in a large data base on pion and photo-induced
reactions. The data on $\omega$ photoproduction are used to determine twelve
$N^*\to N\omega$ branching ratios; most of these are determined for the first
time.
