Integral Representation of the Stellar Surface Structure of the Magnetic   Field
  The surface structure of the magnetic field in stars is one part of the information about the surface inhomogeneities like brightness, movement or chemical composition, which is contained in the integral radiation flux but distorted beyond recognition by losses of information on the topographical arrangement over the surface because of convolution processes and partial invisibility.   Therefore, the complicated processes, beginning with the representation of the map of the surface field distribution and ending with the resulting phase-curves of the integral magnetic field, are simulated by a computer programme. We use this programme as a tool for the analysis of the magnetic field structure out of the really observed data in phase diagrams by variation of the parameters and by fitting the calculated curves to the observed ones.
