Photon beam events are simulated without pileup, so empty events must be inserted. (FilterMCBunches also deletes events unlikely to cause triggers.)

Electron beam data for 2014 run

Filter and space out events

If you're running A' or trident events for which a high trigger rate (more than around 1 trigger per 1000 events) is expected, you should insert empty bunches (or use the no-pileup simulation - see below - which runs much faster but is less realistic in simulating detector timing and efficiencies) since the readout simulation simulates pileup in the detectors assuming input events correspond to consecutive 2 ns beam bunches.
