Thanks, I’ll take a look at that! I think I actually already skimmed it, because those 5 points are familiar.
I wasn’t sure what was meant by the PSF guide star. Is that just the function that selects the speckle in each frame use to shift/align the frames?
Also I wasn’t sure what “sync-resampled” means. Shifted-and-upscaled?
Reading this had given me an idea on how I might implement it myself, but I wasn’t familiar enough with the terminology to know if my algorithm was the same as the one described.
I’ll try reading further into the paper to see if it clears anything up
