Imaging the residuals

Imaging set up is as before, but the image is derived from the 'CORRECTED_DATA' column. The result shown below represents the net image plane effect of the E-Jones matrix for the WSRT. Note that the largest negatives are the ones furthest away from the pointing centre in a radial sense. The central source also leaves no mark because the gain in this direction is unity with and without the simulated primary beam.

This technique is very powerful for determining the levels at which various corruptions affect your final image.
