...
2d histogram NEG_FACE signal vs POS_FACE signal - threshold exist only on positive side - demonstrates that MidPos configuration is correct
LAC POS thresholds
The mean value is peaked at 4 MeV. The temperatures appear not to be uniform across the CALs.
...
There are a few outliers in the distribution. The four extreme ones are:
