Hello Kristian,

in both cases we are reconstructing the same thing: The z coordinate in mm (which is part of the x,y,z coordinate of the lcio::TrackerHit). It is just a matter where we put the origin of the coordinate system: At the cathode in the case of a TPC at a collider, at the end plate in case of a prototype.

Greetings

Martin

btw: All our processors save their name, their parameters as well as the software revision in the run header, so we can reconstruct what has been used to create the data.
