Scientific paper

This letter addresses methods for reducing stellar speckle
interferometry data that require obtaining both the average
autocorrelation and cross correlations of these speckle patterns. It is
shown that these procedures degrade low-frequency results, in
particular, those frequencies near the long-exposure atmospheric cutoff.
