Stokes vectors that would be detected by a perfect high-contrast polarimeter (order = 2 PC) that observed an unpolarized star subject to the polarization aberrations of the GSMTs. These data are normalized to the peak of the I → I component. Each row is a Stokes vector that belongs to one of the GSMTs; (top) TMT, (middle) ELT, (bottom) GMT. These data are plotted on a scale to emphasize the contribution of the polarization aberration to the stellar leakage at the inner working angle. The peak-to-valley (PTV) of the Stokes images is shown on the top-right of each image. Some terms have a PTV larger than 1 because they can take on negative values.
