Photutils

Photutils is a Python library that provides commonly-used tools and key functionality for detecting and performing photometry of astronomical sources. Tools are provided for background estimation, star finding, source detection and extraction, aperture photometry, PSF photometry, image segmentation, centroids, radial profiles, and elliptical isophote fitting. It is a coordinated package <https://www.astropy.org/affiliated/index.html>_ of Astropy_ and integrates well with other Astropy packages, making it a powerful tool for astronomical image analysis.

Please see the online documentation <https://photutils.readthedocs.io>_ for installation instructions <https://photutils.readthedocs.io/en/stable/getting_started/install.html>_ and usage information.
