@article{Sampoorna2011SpectralLP, title={Spectral line polarization with angle-dependent partial frequency redistribution III. Single scattering approximation for the Hanle effect}, author={M. Sampoorna}, journal={Astronomy and Astrophysics}, year={2011}, volume={532} }

Context. The solar limb observations in spectral lines display evidence of linear polarization, caused by non-magnetic resonance scattering process. This polarization is modified by weak magnetic fields ‐ the process of the Hanle effect. These two processes serve as diagnostic tools for weak solar magnetic field determination. In modeling the polarimetric observations the partial frequency redistribution (PRD) effects in line scattering have to be accounted for. For simplicity, it is common…
