MEM and CLEAN Imaging of VLBA Polarisation Observations of Compact Active Galactic Nuclei

The Maximum Entropy Method (MEM) for the deconvolution of radio interferometry images is mathematically well based and presents a number of advantages over the usual CLEAN deconvolution, such as appreciably higher resolution. The application of MEM for polarisation imaging remains relatively little...
