PSFs In the Full FOV. A software package for modeling the point-spread function (PSF) across the full field of view (FOV). Documentation:
Here's another potentially interesting PSF interpolator: https://arxiv.org/pdf/1703.06066.pdf . I have a slight suspicion that this one may be more useful for space than for ground, but would be happy to...
We should have a shapelet model. This will be another LinearModel class, so I'll hold off doing much work on this until @suchyta1 gets farther along on #5 and that...
This is finally the first composite type that I've been working up to. Sum is probably a little simpler than Convolve, so I wanted to start with that. But the...
This PR is a start on some apodization options for Piff. Right now I have fixed things to avoid edge cases for adaptive algorithms.
The recent feature that stars are not removed in fit() only flagged is important for validation tests. Is there a stable version that can be released for 1.4?
Hi! I'm trying to use PIFF to model the psf of a large FOV images. The images are from a QHY411 and have 14200x10650 pixels, I'm cropping the image to...
This pull request has optatmo_psf included. Note that the only unit test included just makes the PSF class, nothing more is implemented yet. In the devel area are two scripts...
@aguinot mentioned to me today that he has a use case where the weight map is not a separate hdu of the image file, but rather its own file. I...
Now that we have non-trivial star selection included in Piff, there are use cases where people might just want to run that without doing the subsequent PSF modeling. I think...
Rubin's been storing its Piff-generated PSFs via pickle thus far, and we all know that's a terrible idea. We've had a few vague thoughts about what we might do instead,...
