PetroFit Documentation
PetroFit is a Python package for calculating Petrosian properties, such as radii and concentration indices, as well as fitting
galaxy light profiles. In particular, PetroFit includes tools for performing accurate photometry, segmentations, Petrosian profiling, and Sérsic fitting. This documentation is intended to serve as a description and guide to the petrofit
Python module. See the Table of Contents below or use the sidebar to navigate this documentation.
