Question Problem with TrackingAction::PostUserTrackingAсtion 

Forum: Event and Track Management
Date: 15 Oct, 2017
From: Mark Chernikov <Mark Chernikov>

Why the tracks of all particles in the TrackingAction::PostUserTrackingA&#1089;tion are called once, but specifically for the electron its track is called several times? The task is as follows: I pass the gamma through the Cherenkov radiator. As a result of the interaction of gammas with the radiator material Compton electrons are formed and the speed of some of them exceeds the speed of light in the medium. It is necessary to find the points of formation of those Compton electrons that formed at least one Cherenkov photon. I do it in the TrackingAction::PostUserTrackingA&#1089;tion. But why exactly the tracks of those electrons that gave the secondary photons then are called into the TrackingAction more than once? It causes a secondary recording of the same coordinate in output file and gives me wrong histogram. An example is taken as a basis: /extended/optical/OpNovice. Geant version: 4.10.03.p02. Thank you.
