Aims: The effect of anisoplanatism in speckle interferometry is studied with emphasis on the autocorrelation function and Knox-Thompson data. Methods: We introduce a method for eliminating anisoplanatism artefacts by statistical analysis of Fourier amplitudes calculated from Knox-Thompson data. Results: With this method, it is possible to suppress anisoplanatism artefacts nearly completely.
