The $\\gamma p\\to\\omega p$ differential cross sections are measured from threshold to the incident-photon energy $E_\\gamma=1.40$ GeV ($W=1.87$ GeV for the center-of-mass energy) with 15-MeV binning in $E_\\gamma$ and full production-angle coverage. The quality of the present data near threshold gives access to a variety of interesting physics aspects.
