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.
