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. © ESO 2007;
