FSD trips this run

Log Number: 4270868Logbook(s): Entry Makers: beneschBody: 

Relatively large number of BLA/BCM trips. Spreadsheets attached for anyone else interested. The only thing that stands out to me is the addition of the Hall C BCM to all the faults on Feb. 5. Prior to that it wasn't present. This is most easily seen in the unexploded csv file. Looking at Figures 3-5 with the integrated loss signal in the lower panel, reducing the integrated loss trip point from 15000 to 1500 seems in order. If this had been the case and we were monitoring this routinely, we would have started looking for the source a day before the vacuum event.
