Signal flip event displays - https://logbooks.jlab.org/entry/3984417
- No sign of strip signals flipping from positive to negative
Implementing analyzer corrections for large negative bias events
- Using the 1/100 full readout events to get a rolling average of the CM during offline analysis
- Use this average to check if the online CM for a particular sample is significantly different.
- Check if a large number of strips pass zero suppression and possibly recalculate the CM.
