Аннотация: Linear polarization measurement in solar flares is discussed from the point of view of the processing technique. Usually, spectropolarimetric investigation of the linear polarization in solar flares is carried out for the line profiles. The results obtained by two methods (either processing of individual profiles or the whole spectral strips) are compared and applied to the observations obtained at the Large Solar Vacuum Telescope (the Baikal Astrophysial obseratory) and at the Ondřejov Multichannel Flare Spectrograph. The results obtained by the second method are comparable by accuracy with the results obtained by the first one. Moreover, it allows to check the instrumental polarization and the polarization behaviour in the nearby objects. However, the profile operating method allows to investigate the polarization effects along the dispersion more carefully.
