Nature of problem:
The program decomposes two-dimensional spectra into the components of interest and that of background, and evaluates such quantities as volumes, two-dimensional positions and widths of the components of interest.

Solution method:
The program inputs the models of the components of interest, which may be constructed using either analytical functions, describing the component shape, or experimentally measured histrograms, representing that shape, and fits the spectrum (divided into parts), estimating the characteristics of the relations between the models and the real images in such a way that these estimates determine at the same time the values of quantities of interest: peak volume, position and width.

The maximum number of components in the analyzed spectrum interval = 12.

Running time:
The average time is about 10 s per component.
