Description

There is no good solution for this. The power spectrum calculation is too slow for today's data collection rate if not binned. This is especially a problem with K3 image where the original shape of image (4092,5760) is harder to transform fast.

Current algorithm bin and trim it to (727,1024) before the calculation in agreement with webviewer default but not ideal for this particular dimension. This is why it has artifact in the power spectrum. In addition, this is in conflict with live redux pipeline of doing power before binning. Therefore, the resolution ring comes out wrong in the viewer.
