Self-calibration image stability for two different sources. The red line displays the progression of the RMS over self-calibration cycles, while the blue line represents the dynamic range (absolute min/max pixel) over self-calibration cycles. The black dashed line is the best calibration cycle according to a combined assessment of the solution and image stability. Left panel: this example corresponds to the self-calibration cycles of the source in the first row of Fig. 11. Right panel: this example corresponds to the self-calibration cycles of the source in the second row of Fig. 11.
