Radial profile of the azimuthally averaged focal plane residuals given the polarization aberrations of spatially-varying coatings on the ELT primary mirror. These data are generated by taking the difference of coronagraphic images with and without segment-to-segment coating variations. These data are computed in I-band for a PC of order 2, and plotted on a log scale to show the change in the absolute value of contrast and highlight the distribution’s features. Each individual trial is plotted in gray, and the RMS of these data is plotted in solid black.
