When running IterativelySubtractedPSFPhotometry, the code fails pretty early on, probably because it tries to use a float position to slice an array. The relevant/end bits of the traceback are below....
It is handy to be able to do photometry with multiple aperture radii with one call, but not so handy that the output is recorded in separate columns, and the...
Given the design of the PSF-fitting routines, which accept initial guesses for the positions as a table with columns 'x_0' and 'y_0', and return a table with columns named 'x_fit'...
I have a project where I need to perform PSF photometry in one image (at fixed x-y positions) and fit for the psf_sigma, and then apply those same psfs to...
*(I'm sorry for flooding the issues with questions. Please let me know if I should give it a rest*) I'm testing the DAOPhotPSFPhotometry class against IRAF's usual tasks for CCD...
I'm trying to generate a model PRF from some ~30 sources using the [DiscretePRF](http://photutils.readthedocs.io/en/stable/api/photutils.psf.sandbox.DiscretePRF.html) class, given an observed frame (`hdu_data`) and source coords (`coords`): prf_discrete = DiscretePRF.create_from_image(hdu_data, coords, size=15, subsampling=5)...
I'm doing PSF photometry on some crowded frames and I've been staring at a screen that shows no changes for well over 10 min now. Could a `verbose` mode be...
The docs say that the `roundlo, roundhi` parameters in the `StarFinder` classes are > applied to both measures of roundness For what I can tell this is applied with a...
IRAF's [starfind](http://stsdas.stsci.edu/cgi-bin/gethelp.cgi?starfind) algorithm allows to set `datamin` and `datamax` values to filter out detections. Would be a nice (and relatively simple?) addition for both star finders.
Uncertainties from PSF fitting was added in #516, but this feature needs to be added to the narrative documentation. cc: @mirca
