This is a bit vague of an issue, but has come up in a few contexts (most recently in #740 and #745), so this is a prompt for someone (probably...

psf

This issue is prompted by discussion at workshop held at STScI Oct 3/4. We settled on some modifications to the PSF photometry machinery that we think end up covering most,...

enhancement

This overlaps somewhat with #443, but is somewhat distinct - the psf photometry machinery should output quality-of-fit information. There are two particular things that I think might be relatively easy...

psf

Right now the PSF photometry machinery depends on doing CircularAperture photometry to make initial flux estimates. That makes sense for many use cases, but there are some situations where you...

psf

Right now the psf block diagram is basically a screenshot from keynote. This is obviously un-maintainable in the face of any future changes. Would be better to instead have it...

psf

Right now the `EPSFFitter` is not a sub-class of `astropy.modeling.fitting.Fitter`. It would be better if it were, as it could then simply be treated as sort of a "drop-in replacement"...

Prompted by the question in #433 (although this has been discussed in various other places), we should develop some functions to do standard sorts of calibrations given the outputs of...

The `PRFAdapter` class currently does a quick-and-dirty integration to integrate over pixels. The `astropy.convolution.discretize_model` is a much more featureful version of this. So `PRFAdapter` should be changed to use that...

This PR is an output of discussions from the April spectroscopic sprint week - there was a consensus there that there should be some light-weight quick-look plot that yields a...

This is a follow-on from #912 - there, in the process of fixing something *else*, @pllim incidentally uncovered an odd test case: https://github.com/astropy/specutils/pull/912/commits/703affd3ca69f630d13718698327da67ce7aa4e8#diff-17f72e2d3ef7080f564b5e8468fabad5155bed36eba4f3ee531c2fee6ac1b6aaL1034 Specifically, if you do moment(order=2,axis=1) on a...
