// Class Description:
|
|
//
|
|
// It is the unified energy loss process it calculates the continuous
|
|
// energy loss for charged particles using a set of Energy Loss
|
|
// models valid for different energy regions. There are a possibility
|
|
// to create and access to dE/dx and range tables, or to calculate
|
|
// that information on fly.
