keyword=Deadtime Check for Longitudinal Production Runs

I checked the deadtime from the Bigbite longitudinal production runs.
For some of the runs the average deadtime for T2, T6 and T8 is over 10%.
Run 1549, which we saw the datamon deadtime fluctuating up to 50%
on average about 23%.

Run       
---------------------
1534         15.1%
1544         14.1%
1549         23.4%

The average deadtime for all other runs was typically 10% or less. The
deadtime for T2 triggers was usually 7% or less, but the deadtime for
T6 and T8 triggers was closer to 15%.
