The Wigner distribution of rotationally symmetric partially coherent light is considered and the constraints for its moments are derived. While all odd-order moments vanish, these constraints lead to a drastic reduction in the number of parameters that we need to describe all even-order moments: whereas in general we have (N+1)(N+2)(N+3)/6 different moments of order N, this number reduces to (1+N/2)(1+N/2) in the case of rotational symmetry. A way to measure the moments as intensity moments in the output planes of anamorphic fractional Fourier transform systems is presented.
