caustic

caustic is a code designed for Bayesian modeling of single-lens gravitational microlensing events using the PyMC3 probabilistic programming language which enables the use of gradient based inference algorithms such as Hamiltonian Monte Carlo. It is built on top of theano, exoplanet and Astropy.

The code is being publicly developed in a repository on GitHub.
