The full frame mode of operation is widely used for optical astronomy in order to obtain the greatest focal plane coverage. In X-ray astronomy this mode has a disadvantage in that for the relatively shorter image integrations required to maintain a photon counting mode, smearing of the images occurs during readout when the photons continue to fall on the moving charge pattern. ...
