Overview ======== Introduction ------------ Photutils contains functions for: * performing aperture photometry * performing PSF-fitting photometry * detecting and extracting point-like sources (e.g., stars) in astronomical images * detecting and extracting extended sources using image segmentation in astronomical images * estimating the background and background RMS in astronomical images * centroiding sources * creating radial profiles and curves of growth * building an effective Point Spread Function (ePSF) * matching PSF kernels * estimating morphological parameters of detected sources * estimating the limiting depths of images The code and issue tracker are available at the following links: * Code: https://github.com/astropy/photutils * Issue Tracker: https://github.com/astropy/photutils/issues Like much astronomy software, Photutils is an evolving package. The developers try to maintain backwards compatibility, but at times the API may change if there is a benefit to doing so. If there are specific areas you think API stability is important, please let us know as part of the development process.
