 `PSFMachine` is an open source Python tool for creating models of instrument effective Point Spread Functions (ePSFs), a.k.a Pixel Response Functions (PRFs). These models are then used to fit a scene in a stack of astronomical images. `PSFMachine` is able to quickly derive photometry from stacks of *Kepler* images and separate crowded sources.
