High-resolution photographic Stokes polarimetry of small-scale magnetic flux

TL;DRAbstract

Simultaneous photographic spectra of the Fel 6301.5 and 6302.5 lines in LCP and RCP over a small scale magnetic feature have been analyzed in terms of Stokes I and V profile parameters. Special attention was paid to the reduction of effects due to the non-linearity of the film and to the instrumental polarization. We do not find a continuum enhancement in the magnetic filed region and we see magnetic as well as non-magnetic line gaps. The small scale magnetic region consists of two polarities, but only the dominant polarity seems to be correlated with the line gap.
