Illustration of the effect of CTI at post mission EOL (i.e. 6.5 yr after commissioning) using the Short model. The plot shows a centrally placed 200 × 200 pixel CCD subfields of PIC stars from the LOP south including cosmic rays simulated using a hit rate of 10 events s⁻¹ cm⁻¹. The images has been clipped by a 2σ cut and then normalised for illustrative purposes. The readout register is located towards the bottom of the image.
