摘要：
A method for differential photometry of speckle-interferometric binary and multiple stars is presented. Both the accuracy and sources of systematic errors of the method are analysed. The photometric accuracy ranges between 0.(m)02 and 0.(m)20, depending on the atmospheric seeing, the brightness and the separation of the system components. A comparison between our magnitude differences and those of other authors is presented.
