Radio observations give the only way to study processes of particle acceleration and energy release in the outer corona. However, a variety of emission mechanisms and their dependence on parameters of the emitting electrons makes extremely difficult the study of the solar processes without knowledge of information which can be provided by other spectral ranges. Namely, the magnetic configuration given by magnetograms, temperature and density distribution given by X-ray observations contribute essentially to the correct interpretation of radio data. This is the reason why the study of the solar activity based on radio observations is connected with use of multi-spectral data. Thanks to development of the Internet, astronomers can use now, in fact, data of all ground-based and orbital observatories.
Experience shows that data processing is performed, as a rule, in a few stages.
Subsequent stages include previewing, selection of foremost records, their correlation with data obtained in other ranges of the emission, measuring of parameters of radio sources and, finally, estimates of physical conditions and model calculations. The first level of data reduction, as a rule, is executed by routine instrument-specific software. Subsequent data processing is often carried out under conditions when not only techniques, but also an approach to the solution of a particular physical task are not clear. These conditions suggest interactive work when various techniques of data processing can be tested. Taking into account its advantages, we have chosen it as the base in solving of our tasks.
