RoadRunnerModel# RoadRunner transit model example I - basics Import the model Example 1: simple light curve Example 2: heterogeneous light curve RoadRunner transit model example II - custom limb darkening Import the model Approach I: give a limb darkening model as function Approach II: implement the limb darkening function as a subclass of LDModel RoadRunner transit model example III - LDTk-based limb darkening Import the model Example 1: single passband Example 2: multiple passbands RoadRunner transit model The basics Initialisation The weight array The average limb darkening occluded by the planet The transit signal Derivatives Multicolour photometry and transmission spectroscopy Future optimisations Acknowledgements
