High-fidelity wideband VLBI polarimetry

We will discuss about wideband and multiband VLBI observations taken with linear-polarization feeds (the simplest hardware polarimetry for wide bands), and how these observations can be calibrated and fringe-fitted with special software, in order to produce full-polarization images with a high fidelity. We will show results from real observations, taken with the VGOS array, and discuss about future applicability of these algorithms in future VLBI arrays.
