The cross section asymmetry \ensuremathΣ has been measured for the photoproduction of \ensuremathπ\ifmmode^∘\else\textdegree\fi mesons off protons, using polarized photons in the energy range E_\ensuremathγ=0.5--1.1GeV. The center-of-mass angular coverage is \ensuremathθ_\ensuremathπ*=85\ifmmode^∘\else\textdegree\fi--125\ifmmode^∘\else\textdegree\fi with energy and angle steps of 25 MeV and 5\ifmmode^∘\else\textdegree\fi, respectively. The obtained \ensuremathΣ data, which cover the second and third resonance regions, are compared with existing experimental data and recent phenomenological analyses. The influence of these measurements on such analyses is also considered.
