Not able to use EFFICIENCY with G4LogicalBorderSurface

[loydms]

See the answer to this question

Optical properties

what is the meaning of the REFLECTIVITY and EFFICIENCY in the optical properties of the surface? G4double reflectivity[num] = {0.3, 0.5}; G4double efficiency[num] = {0.8, 1.0}; G4MaterialPropertiesTable *myST2 = new G4MaterialPropertiesTable(); myST2->AddProperty(“REFLECTIVITY”, ephoton, reflectivity, num); myST2->AddProperty(“EFFICIENCY”, ephoton, efficiency, num);

I believe it depends on what model you are using, and I am not sure from your code snippet what model you are using
