Abstract
The photon structure function F-2(gamma) has been measured with data taken by the ALEPH collaboration at LEP centre-of-mass energies root s = 91 GeV w ith (Q(2)) of 9.9, 20.7 and 284 GeV2 and root s = 183 GeV with (Q(2)) Of 13 .7 and 56.5 GeV2. For the data at root s = 183 GeV a two-dimensional unfold ing method employing the principle of maximum entropy is used, which reduce s the errors compared to one-dimensional methods.
