- // As the innermost detector in ALICE, the Inner Tracking System "impacts" on
- // almost all other detectors. This involves the fact that the ITS geometry
- // still has several options to be followed in parallel in order to determine
- // the best set-up which minimizes the induced background. All the geometries
- // available to date are described in the following. Read carefully the comments
- // and use the default version (the only one uncommented) unless you are making
- // comparisons and you know what you are doing. In this case just uncomment the
- // ITS geometry you want to use and run Aliroot.

- // ITSgeometry.tme) in a format understandable to the CAD system EUCLID.
- // The default (=0) means that you dont want to use this facility.
