Instantaneous Strehl ratio and the average dark-hole contrast as a function of time. The setup is the same as in the previous figure. The imaging camera is read out every 200 ms as indicated by the vertical, dashed, gray lines. The science image and diversity image are first cleaned by removing the halo and speckle terms and are then used to estimate the NCPA. The dashed blue and red lines indicate the average Strehl ratio and contrast, respectively, for the case when there are no NCPAs.
