Here is the reconstructed energy vs ADC 0+ and this is the reconstructed energy vs ADC 0-. A few Xtals reconstruct energies below a MeV. A few pathological Xtals can be identified here:
- lay==0 && col==5 && tow==layer 0 column 5 tower 8
This is the Xtal that shows the horizontal stripes between 500 and 600 ADC counts in the second plot. Both ADC0+ and ADC1+ show unusual distributions.
