|
|
// 03-12-02 V.Ivanchenko fix a bug in model selection
|
|
// 20-01-03 Migrade to cut per region (V.Ivanchenko)
|
|
// 27-01-03 Make models region aware (V.Ivanchenko)
|
|
// 13-02-03 The set of models is defined for region (V.Ivanchenko)
|
|
// 26-03-03 Add GetDEDXDispersion (V.Ivanchenko)
|
|
// 13-04-03 Add startFromNull (V.Ivanchenko)
|
|
// 13-05-03 Add calculation of precise range (V.Ivanchenko)
|
|
// 21-07-03 Add UpdateEmModel method (V.Ivanchenko)
|
|
// 03-11-03 Substitute STL vector for G4RegionModels (V.Ivanchenko)
|
|
// 11-04-05 Remove access to fluctuation models (V.Ivanchenko)
|
|
// 10-01-06 PreciseRange -> CSDARange (V.Ivantchenko)
|
|
// 20-01-06 Introduce G4EmTableType and reducing number of methods (VI)
|
|
// 13-05-06 Add GetModel by index method (VI)
|
|
// 15-03-07 Add maxCutInRange (V.Ivanchenko)
|
|
// 08-04-08 Simplify Select method for only one G4RegionModel (VI)
|
|
// 03-08-09 Removed unused members and simplify model search if only one
|
|
// model is used (VI)
|
|
// 14-07-11 Use pointer to the vector of cuts and not local copy (VI)
|
|
//
|
|
// 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.
