Pion shower shapes. MC/Data Ratio of the fraction of energy in each longitudinal layer.
The MC/Data ratio is shown as a function of the beam energy. Each plot shows the fraction of energy in each longitudinal layer (long respectively 1.5/2.9/3.0/2.8 lambda). Results obtained with Geant4 9.4. Comparison of two physics lists.
