This subsysreco module dumps the E_T values for all EMCal towers in a ttree named cemc_et.
The E_T value is calculated as ET = tower->get_energy() / cosh(eta_from_vertex).
The eta is evaluated
This ROOT macro reads a ttree and saves an image file (.png) of Lego plot event by event.
Usage:
[]$ root 'DrawCemcLego.C("/sphenix/user/ryotaro/DisplayLegoPlot/output/0/0-00000.root")'
