First, the geometry has to be constructed. Assuming this is already done, we describe the data processing.
First, the geometry has to be constructed. Currently the ACTS geometry is constructed and tested as part of the athena pipeline.
The tracking surfaces can be viewed in a cad program using the output `tracking_geometry.obj` file the reconstruction_benchmarks pipeline.

Assuming this is already done, we describe the data processing.
