Abstract
In this paper, the statistical error courses in the intensity autocorrelation function are simulated and the influence of these errors on size distribution reproducibility is checked. As a numerical method, the constrained regularization method with the Contin program was used and autocorrelation functions were calculated on the basis of the monomodal Schulz distribution. The influence of the regularization parameter α on the recalculated size distributions has also been checked. It has been found that the reproducibility of original size distributions can be lost because of the existence of slow-frequency components in noisy data.
