DOPPLER-ZEEMAN MAPPING OF MAGNETIC CP STARS - SOLUTION OF THE INVERSEPROBLEM SIMULTANEOUSLY FROM THE STOKES-I AND STOKES-V PARAMETERS

An efficient method has been developed for solving the inverse problem of Doppler-Zeeman mapping of magnetic, chemically peculiar stars. A r egularized iteration method is used to simultaneously solve the integr al equations for the Stokes I and V parameters. The validity of analyt ical fits for the local profiles of the Stokes parameters is substanti ated. The algorithm has been tested on models. It is used to simultane ously obtain a map of the distribution of a chemical element and the p arameters of an arbitrarily shifted magnetic dipole from the observed I and V profiles.
