Consistent galaxy colors with
Gaussian-Aperture and PSF photometry

  • Arun Kannawadi


Gaussian-Aperture and PSF photometry algorithm measures consistent colors for extended sources such as galaxies that are largely independent of seeing. This technote briefly presents the mathematical description of the algorithm and focuses on its implementation in the Rubin Science Pipelines. This document also serves as a reference for several of the analytical calculations that are tested in the unit tests.
