Comparison of LSST and DECam Wavefront Recovery
... On the wavefront sensor images from each exposure, we typically have tens of donut images on each of the eight sensors. Because the wavefront varies across the focal plane, we only use images from adjacent CCDs to form the intra- and extra-focal pairs. Saturated images are excluded from further use. ...
