0015  *  2: ditto, but for a particle travelling to the 3D center of the wire.
0016  *     (This mode is avaliable for comparison with older data which were
0017  *     produced in this way)

0019  *     nominal IP to the 3D center of the SL. Use this, unless you
0020  *     really know what you are doing.
