Description
The current zogy implementation is assumed to have issues in:
- Understand how the variance plane should propagate in zogy (convolution then whitening decorrelation).
- Correct padding and centering of images and PSFs in Fourier space opeartions. (numerical accuracy in DFT vs. origin location and periodicity assumptions)
- Correct calculation of the difference image variance plane. (variance of image k-space components vs. k-space components of variance plane)
- zogy.py:384 padSize argument usage
