Left: image of β Dor at 10 µm at the position where the bright star was observed in the previous two observations at 5.6 and 7.7 µm. The persistence images of the star in the two positions can be seen in low contrast as well as that of the slew between positions. Right: identification of the pixels that are marked as “hard” saturated in the first position observation at 5.6 µm. We can see the persistence image matches well the image structure of the hard saturated pixels from the image.
