add simple example showcasing the need for the SCRIP algorithm

1

like we did in the R package, we should show examples where general solvers (from e.g., `scipy.optimize`) are not able to or are too slow to solve the non-convex risk...

The user should be able to control ``sub_shape`` parameter passed to ``subtract_psf`` inside the ``nstar`` method.

Allow the fitting region to be circular in PSF Photometry

1

Currently the fitting region is defined by the ``fitshape`` parameter which defines a rectangular region around the (initial guess) center of the source. It would be great to be able...

Rename 'flux' column in tables generated by ``StarFinderBase`` objects

1

I think it makes sense to rename the ``flux`` column in tables generated by ``StarFinderBase`` objects to something like ``flux_peak_density``. I'm saying this because the name ``flux`` induces users to...

group stars from different iterations in the PSF Photometry algorithms

1

I think it would make sense to put stars which are identified in different iterations, but which overlap each other, in the same group. Further, one could re-fit that group...

Expose the mean model for CBV correction to the user

1

Sir @barentsen mentioned today that one could jointly fit for the CBV weights and an astrophysical variability (so that the astrophysical signal wouldn't be taken out by the CBVs) by...

We should be able to come up with something that would smartly choose the number of CBVs. A tradeoff between CDPP and overfitting... In the example below, I used the...

i.e., only the ``flux`` and ``time`` attributes are stitched.
