Detailed Description

This class describes energy loss material effects in the ATLAS tracking EDM.

Energy loss through ionisation and/or radiation leads to a change (reduction) of the momentum. It uncertainty can be asymmetric in this class. The quantity is energy since the calculation from energy to momentum can be done better inside the MEFupdators (which know the particle hypothesis) than the DetDescr tools.
