EMECCell Class Reference

A Cell of the electromagnetic endcap calorimeter readout geometry This class represents a single EMEC Cell. These cells are specified by phi and eta boundaries, the latter which corresponds to an inner and outer radius computed from and effective focal length. Those numbers come from the database via the EMEC DetectorManager. More...

Detailed Description

A Cell of the electromagnetic endcap calorimeter readout geometry This class represents a single EMEC Cell. These cells are specified by phi and eta boundaries, the latter which corresponds to an inner and outer radius computed from and effective focal length. Those numbers come from the database via the EMEC DetectorManager.

Use the EMEC Cells through EMEC Cell Links please!!! This will free the memory used by the cell when the last link to the cell disappears.
