Omega background (produced in the target and downstream the beam line)

Old simulation

1M events for each runs are thrown, the incident photon-energy distribution follows the run flux distribution

Downstream the beamline means at the location where the FDC is the beamline

New simulation

g He4 to w He4 and w to gpi0 (2019-01 and 2022-08) or w to pi0pippim (2022-08)
