The hadronic photon structure function Fγ2(x,Q2) is measured from data taken with the ALEPH detector at LEP. At centre-of-mass energies between s√=189GeV and 207GeV an integrated luminosity of 548.4pb−1 is analyzed in two ranges of Q 2 with ⟨Q2⟩=17.3 GeV2 and 67.2 GeV2. Detector effects and acceptance are corrected for with a Tikhonov unfolding procedure. The results are compared to theoretical predictions and measurements from other experiments.
