None Allocation of a hit to a detector: PreStepPoint and PostStepPoint

Hi,

I have two questions about energy deposits which are not clear in the user guide:

I am currently allocating a "hit" to a sensor if the PreStep Point is in that sensor volume. I then get the total energy deposit for that step. This seems to be how it is done in the examples (e.g. ExN04).

But if the PostStep point is outside of the sensor volume, part of the energy deposit should not have been allocated to the sensor. Is this an unavoidable error in the results (I assume it is probably small for large sensors)?

Second question: in G4Step there is:

GetTotalEnergyDeposit()

GetNonIonizingEnergyDeposit()

Is it correct that "total energy deposit" here equals ionizing plus nonionizing?

Many thanks,

Edward.
