After the "lucky imaging" portion of the pipeline is done, we should perform various photometric and astrometric analysis utilizing the much higher S/N of the collapsed frames. In a sense, after the frame collapsing we are at the starting point of most traditional post-processing pipelines.
In the collapsed data, we can get many data products from PSF fitting the star or the satellite spots.
Fitting the PSF provides refined centroids
The PSF centroid can be used to get the refined peak -> Strehl ratio
The refined centroids can be used to extract a PSF stamp from a data cube, which can then be used for post-processing
