Today, XENON releases data from the XENON1T S2-only / light dark matter search published in Physical Review Letters 123, 251801 (2019). You can find the data release at:

• Zenodo: https://doi.org/10.5281/zenodo.3982637
• GitHub: https://github.com/XENON1T/s2only_data_release

This includes observed events, background models, and response matrices to construct arbitrary signal models. Together, these allow researchers to constrain their own dark matter models using the XENON1T S2-only data. We included a jupyter notebook example to help you get started.

We look forward to seeing what models the community will think of!
