L1B0a thresholds



On Friday, STEREO had two aliveness tests (for FM1 and FM2), and we were able to test threshold effects for L1B0a. After the MSU run, I've noticed that there are lots of priority buffer 25 (bad live stim) events, about 7% of PB 24 (good live stim), whereas the ratio was <1% at MSU. My investigation showed the bad live stim events had second L1B signals in L1B0a, and it was proposed that we raise L1B0a thresholds to get rid of "crosstalk". I watched the data streaming into skadi in Room 5 with Branislav, and we could easily see the priority buffer 24 and 25 counts shift with higher threshold settings.

I sent out the plots and reported the results today.
