Two methods for performing indirect Fourier transformation of small‐angle scattering data have been introduced by Glatter [ J. Appl. Cryst. (1977), 10 , 415–421] and Moore [ J. Appl. Cryst. (1980), 13 , 168–175]. These two methods are here compared to one using maximum entropy. The methods have been applied to simulated as well as experimental scattering data. The comparison of the three methods for the simulated data shows that the maximum‐entropy method and the method of Glatter give similar results, which agree well with the original distributions. The method of Moore occasionally gives results which have artificial oscillations.
