BLA trips

A BLA trip just occurred so I looked at the signals. Instantaneous loss on the scale shown in figure 1. Constant in figure 2 is 1.5 uA so I don't see why there should have been a trip with 24 uA to C only. Integrated loss and the two currents are on a 0-1250 unit scale. There are spikes in figure 1 which exceed 1.5 uA in either direction so those trips should have occurred. Figure 3 shows BLA trips in light purple.

Figure 1 reflects the three reductions I just made to ODVH on the cavities with highest true arc faults. It also shows that the energy lock zone, 1L19, is running low in general. Change fudge slightly?

Figure 2 reflects the one ODVH reduction just made. Energy lock zone 2L19 is running a bit higher than lem would set. Increase fudge to 0.96 or even 0.965 since 2L19 is 2 MV/m or 1 MeV/c high? fudge had been at 0.96 for the first five days of the month.

Figures 4-7 show options for both NL and SL.
