The WOSA method can be implemented for PSD to reduce variance in the PSD estimate. The subapertures can also be shifted away from the center an extra amount to enable robust PSD calculation for data with annular support.

Interferogram.mask can be used for inspiration on how to embed a (shifted) circular mask. The data should be cropped before feeding through the PSD function. Each subapert

Would be nice to easily export all emails of mentors so that we can update the private mentors mailing list. The system takes I think a text file with a list of emails one per line, or a cut/paste into a text box in the same format. You might be able to include a displayname in the import.

Currently psf.draw(x,y) centers the PSF profile at the sub-pixel values of the provided x,y positions.

This is sometimes a desirable feature, but not always. We should make it easier for the user to specify how they want the PSF image centered. I'm proposing a new center keyword argument to the draw command with the following options:

center=None   # (default) the current behavior u

Dear all,

I am discovering this excellent software, and its good documentation (a really cool source of informations for me).

As there does not seem to be much opensource tool to analyse astro image quality on linux (like ccd inspector), I was impressed by the quality of this software.

I am definitely interested in testing it and using it. at some point, I also would like to implement pro
