batman:
Bad-Ass Transit Model cAlculatioN

Welcome to the documentation for batman, a Python package for fast calculation of exoplanet transit light curves. The package supports calculation of light curves for any radially symmetric stellar limb darkening law, using a new integration algorithm for models that cannot be quickly calculated analytically.

In typical use, batman can calculate a million model light curves in well under 10 minutes for any limb darkening profile.

A paper describing batman is up on arXiv; please cite it if you make use of the package!
