Hello,

to the second point: I don't think there is an ambiguity. The maximum distance an electron can drift is from the cathode to one of the endplates.

to the first point: The two parameters are not standard gear, is that correct? For the time being we should assume two half TPC with equal drift distance, the origin located at the cathode. Offsets from the nominal vertex can be handled by correction processors later. And I don't see why one should like to have the origin at 2/3 of the drift length of the left half TPC.
So I would still like to use "getMaxDriftLength()".

btw: How have you solved the problems that the two halves are "looking" into different directions?

Greetings

Martin
