the energy released in the two calorimeters seen from the
incoming beam direction. The e.m. calorimeter is readout 2-dimensionally
The energy released in each of the 13000 2x2 cm cells
is color-coded in light and dark blue (lower and higher energy released).
One sees two separates clusters produced by the two pions. Notice how part of the energy of the rightmost pion is lost into the central hole of the calorimeter, that houses the beam-pipe.
The cell in yellow is the one for which the pulse-shape is shown in the
Bottom-Right plot.
One also sees, in purple on the sides, the histograms of the energies
released in the x and y view of the hadron calorimeter
