After we changed the beam current from 10uA to 12uA,
triggers rates have changed as follows:

 Trigger | 10uA rate  | 12uA rate | rel. change
--------------------------------------------------
   T3    |   1.017 E4 |  1.228 E4 |  1.2
   T5    |   7.114 E2 |  9.78 E2  |  1.4

From this we see that rate in T5 has not changed linearly
as T3 did. This relative change is also observed in the attached
trigger plots. When we look at the T5-trigger TDC plot we can see
that the the number of random coincidences has increased a bit,
while the "physics peak" stayed the same. 

In the rest of the plots we did not observe any significant change.
