Abstract: 
Problems arising in the analysis of spacecraft measurements made in the Earth's magnetosphere are discussed. Data processing should take into account the properties of plasma regions where the measurements were made. We give an overview of the most widely used experimental criteria, empirical models, and the features assumed to be characteristic of the magnetosphere regions. Preliminary scheme of the data analysis from the viewpoint of space physics is sketched. The study was made in the framework of the Interball-Tail data processing.
Keywords: Earth's magnetosphere, Interball-Tail, spacecraft measurements
