Polarization Imaging with LOFAR
Polarimetry with LOFAR is somewhat different from polarimetry with, for example, the VLA or WSRT. At LOFAR frequencies, Faraday rotation is much stronger than at for example L band. The ionosphere in particular is a big nuisance. Moreover, the polarized response of (a group of) phased array stations is very different from the response of (a group of) parabolic dish antennas. This lecture focuses mainly on the physics of low frequency polarimetry, and how it affects observation planning, data processing, and imaging.
