Extended Data Fig. 1: The BDT distribution for events with a reconstructed energy above 4 PeV.

The plotted events are required to be consistent with a cascade hypothesis based on the goodness of fit. The PEPE event selection requires a BDT score greater than 0.5. Good data–MC agreements were observed across the background and the signal region. See Methods for details.
