The cleanReadout needs to be turned off. It doesn’t do a good job. The FFT version does better on the individual frames, but the difference in background level of the 4 quadrants messes up the source detection. That is “fixed” by setting mask=True in detectSources. Regardless, the final stack is still bad in a similar way as for the std cleanReadout.
