Abstract
This paper is devoted mainly to a method of determining the gradient of magnetic fields. Utilizing the numerical solution of the equations of transfer of the Stokes parameters, we have calculated quantities characterizing the asymmetry and the amount of rotation of the wings of the “o” and “e” profiles of the magnetically sensitive line Fe Iλ 6302.499 as functions of the magnetic field gradient. The results of calculations have been verified with our own spectrophotometric observations of a large sunspot. The range of validity of the method is discussed, and the possible influence of the presence of magnetic field gradients on the observational data of magnetographs is investigated.
