BEvAn — COSI activation simulations MEGAlib simulation files backing cosi-betadecay/BEvAn, a physics-based likelihood classifier that tags each simulated COSI event as a β⁺ / positron-annihilation signal (back-to-back 511 keV photons) or background from its Compton kinematics. All events come from a cosima activation simulation (BeamType Activation, DecayMode ActivationBuildup): cosmic-ray protons irradiate the instrument, the activated isotopes decay, and the β⁺ emitters among… See the full description on the dataset page: https://huggingface.co/datasets/aryaraeesi/BEvAn-data.
