I have a low surface brightness galaxy.  The maximum pixel value is 0.39, the minimum pixel value is -0.32. Then I use photutils.ellipse.fit_image() to fit the galaxy. There is...
Strangely, the model PSF constructed with `EPSFBuilder` always has an all-zero row and an all-zero column next to the edges of the model PSF image. Here is how it looks...
I have made and been using the pill type aperture. ([here](https://github.com/ysBach/ysphotutilpy/blob/master/ysphotutilpy/aperture.py#L445). I named it `PillBox` as it is a combination of elliptical and rectangular("box") aperture, but I think `Pill` is...
I want to use ePSF to refine star center positions, then feed to Scamp for better wcs to do SWarp. But im not clear how EPSFBuilder work on dither images,...
See related unsolved issue: #1369 But this is a feature request not strictly related to that bug. It would be great if we could limit the flux uncertainty calculation only...
Hello. From an IsophoteList object, I can create a table though the to_table method. I was wondering if there is a way to do the opposite of that, given a...
Hi, I am using Photutils extensivly to perform photometric analysis and i am quite happy with your program. I recently encountered a really boxy galaxy, so the normal isophotes left...
Hi, It would be nice if support for PSFEx psf file can be added in photutils (at least in limited capacity). The structure of the variable psf file is a...
Fitted PSF photometry fluxes can go negative. Can we include a mechanism to reject them using public methods? Right now, you can reject them, but it requires modifying a private...
photutils version: 1.12.0 In file isophote/model.py, Line 124, Col 64  There is a "`/ 4.0`" in the calculation of `harm` (contribution to isophote intensity from high harmonics) that takes...
