Important Changes in the Histogram

Deviations in the cross talk histograms may be due to changes in the muon and positron energies. More energetic particles cause larger signals and therefore have a greater capability of inducing cross talk. Abnormal amounts of cross talk (hot wire) could point to problems with the electronics or cabling. Similar to the wire occupancy histograms, changes to the position of the occupancy peak, or width will be due to movement or focusing of the incoming muon beam.
