The implementations of the planet injection, source counting and ROC curve generation algorithms are included in the open source Vortex Image Processing package for the sake of transparency and fairness. Other code related to the data challenge is available at the Data Challenge Extras repository. Here we also share a Python script (DC1_codalab_starting_kit.py) that illustrates how to create the outputs to be submitted for participating in the data challenge.

The extras repository also contains a data challenge starting kit, in the form of a Jupyter notebook (DC1_starting_kit.ipynb), which explains in detail the source counting procedure on detection maps (to get the true and false positives). The starting kit can also be executed on the cloud thanks to Binder. This implementation shall serve as a reference for future studies on image processing algorithms for direct imaging of exoplanets.
