Actual and estimated NCPA with contrast control and not including halo and speckle terms. Top-left: actual NCPA phase aberration. Top-right: estimated NCPA phase after 600 ms when directly using phase-diversity-based phase retrieval on the science and diversity images without clean up. Bottom: Residual phase aberration after 600 ms. The residual aberration has been magnified by ten to be more visible in the figure.
