This configuration replicates the beam configuration in the following file: 25ns_2748b_2736_2452_2524_288bpi12inj.sch.

See the following ticket for more details: https://its.cern.ch/jira/browse/ATLASSIM-1788 Any of the filled bunch crossings can be chosen as the central bunch crossing, so the timing of the out-of-time pile-up will vary significantly from event to event. Cavern Background is independent of the bunch pattern. (Compatible with 25ns cavern background.)
