catwoman: A transit modelling Python package for asymmetric light curves

catwoman is a Python package that models asymmetric transit lightcurves where planets are modelled as two semi-circles with different radii in any orientation, for any radially symmetric stellar limb darkening law.

catwoman uses the integration algorithm developed for the batman package (Kreidberg 2015), from which catwoman builds upon.

catwoman was peer reviewed by JOSS (Journal of Open Source Software) and Jones & Espinoza 2020 can be viewed here

catwoman has been demonstrated and used in Espinoza & Jones 2021 .
