Data set |$D_{\rm 1}$|⁠. Top: comparison of image-plane results with the ground-truth input at two representative frequency channels, as an example. The rows contain Stokes I (top), the polarization fraction (middle), and the polarization angle (in deg; bottom). The rows contain Stokes I, Q, and U from top to bottom. Bottom: comparison of source-plane results with the ground-truth input. The rows contain Stokes I (top), the polarization fraction (middle), and the polarization angle (in deg; bottom).
