keyword=Deposited-energy gap in BB shower rows
The figure shows the energy deposited (horizontal axis) plotted against
the row of shower blocks (vertical axis). We see a clear gap around rows
17-22, corresponding to the trigger hole observed earlier.
The presence of a gap in the energy-deposited data supports Kalyan's
conclusion that the gap represents real physics, i.e. a separation
between pions and good electrons.
