            From the notebook https://github.com/lsst-ts/ts_analysis_notebooks/blob/develop/aos/vignetting/wepVignettedPerformanceLimits.ipynb

            Vignetting affects the Zernike estimation beyond a field radius of 1.813

            The amount of the detector cutoff (not useable for donut estimation)  is 4.9906 percent

             

            Zernike's for donuts compared to the OPD as a function of radial distance from the center of the LSST pointing

             

            Image quality for the convergence of the closed loop (for the faintest stars selected by the AOS - 15.9 mag) as a function of radial distance from the center of the telescope pointing

             

             

            Example of vignetting as a function of radial distance and the area excluded if we place a limits of 1.813 degrees for the selection of donuts
