A cell of the electromagnetic barrel calorimeter readout geometry This class gives dimensions and positions, and indices of an electromagnetic barrel calorimeter readout cell. Positions are in local coordinates (local to a "big piece", or in this case the EMB half barrel). Use the EMB Cells through EMB Cell Links please!!! This will free the memory used by the cell when the last link to the cell disappears. More...
