The photoproduction of $\omega$ mesons off the proton has been studied in thereaction $\gamma p\to p\,\omega$ using the CEBAF Large Acceptance Spectrometer(CLAS) and the frozen-spin target (FROST) in Hall B at the Thomas JeffersonNational Accelerator Facility. For the first time, the target asymmetry, $T$,has been measured in photoproduction from the decay $\omega\to\pi^+\pi^-\pi^0$,using a transversely-polarized target with energies ranging from just above thereaction threshold up to 2.8 GeV. Significant non-zero values are observed forthese asymmetries, reaching about 30-40% in the third-resonance region. Newmeasurements for the photon-beam asymmetry, $\Sigma$, are also presented, whichagree well with previous CLAS results and extend the world database up to 2.1GeV. These data and additional $\omega$-photoproduction observables from CLASwere included in a partial-wave analysis within the Bonn-Gatchina framework.Significant contributions from $s$-channel resonance production were found inaddition to $t$-channel exchange processes.
