| Abstract: | A sample of 36 S-component sources observed by the radio telescope RATAN-600 was compared with calculations of gyromagnetic emission and bremsstrahlung based on recent sunspot models. The diagnostic possibilities of the spectral distributions in the radio flux, the degree of polarization, and the source sizes for the estimation of magnetic scale heights and other source parameters were checked by different methods.Depending on the magnetic field structure, the observations show different types of polarization spectra. Most regular spectra and highest values of the degree of polarization were observed from sources above the leading part of the associated spot group. Magnetic scale heights were found to be intrinsically associated with the source size of the gyromagnetic emission.The flare production rate of active regions appears to be related to their S-component flux and magnetic scale heights. |
