Data in GIPSY is stored in so called sets . A set consists of two components: an image component and a descriptor component. These components are stored in separate files, but in GIPSY they are always used together. The image data is stored in a `crystalline' structure with a virtually unlimited (up to 20) number of dimensions. ... Within a set subsets can be defined. ... The figure below shows the possible subset types in a three-dimensional set, a `` cube '': . ...

The observation of active regions with RATAN-600 and the Beijing Astronomical Observatory spectrograph in the decimeter wave band shows an existence of a long-term non-thermal emission of active regions in continual (a halo) and flaring (flares and micro flares) components. The observation-compatible models have been devised specifying the nature of continuum as a radiation originating in the non-linear interaction of plasma waves at the upper-hybrid frequency. ...
