Example of the image improvements after applying extra self-calibration with only Dutch core and remote stations at 6″ on facet 17 (see Fig. 14) in a 0.4° × 0.4° cutout image. Cycle 0 has only DI solutions applied, cycle 3 had the first round of scalarcomplexgain solve where both phases and amplitudes are calibrated, while cycle 10 shows the result after the final round of self-calibration.
