Simulated VIS exposure. The left image shows the entire 6 × 6 mosaic of detectors and the right image contains a zoomed in fraction of a quadrant, where the multiple effects can be seen such as bright stars, galaxies, cosmic rays, a complex PSF model, a ghost from a nearby star, saturation bleeding, and the trails of the Charge Transfer Inefficiency (CTI) increasingly visible in the readout direction. In this image, the end-of-life model for the CTI was adopted. A linear scale around the median with only 30 ADUs of range was used to visualise the subtle instrumental effects present in the simulation.
