PSF get_clip coordinates #185

Closed guynir42 closed 5 months ago

guynir42 commented 5 months ago

It is not clear (to me) if the center of the image is (0,0) or (shape/2, shape/2) when calling functions of the PSF object, like get_resampled_psf() and get_clip().

I've used (0,0) in my last PRs and it works better than using the image shape (maybe I got the image shape wrong, too). This requires some investigation.
