The trigger setting for 1415 was 'elastic_10-15' which accepts only
coincevents with the proton in paddles 10-15 (left or right) (so a hit
on 0-6 on one side, and 10-15 on the other side).
The trigger setting for 1416 was 'all_coincs' which accepts all
left-right coincidences. all cerenkovs were X in both cases.
I'll start looking into this asymmetry stuff today.
