LAC POS thresholds

The mean value is peaked at 4 MeV. The temperatures appear not to be uniform across the CALs.

LAC distribution per CDE

There are a few outliers in the distribution. The four extreme ones are:

The LAC is well-defined, with sufficient statistics, so the threshold is real and might need to be corrected.
