Fig. 2

The nonunitary Mueller matrices in
cause the mapping in Eq. (19) to not be a convolution operator. The left panels shows the dirty image

obtained after applying
to the visibilities. The image plane correction
is displayed in the central panel and the corrected image
is shown in the right panel. As explained in Sect. 3.5 the modified mapping is approximately a
direction-dependent local convolution function.
