/** \page global_coordinate_system global coordinate system
 *
 *  The global coordinate system of the MC simulation is defined as follows:
 *  \li X-axis is in the horizontal direction beam-left,
 *  \li Y-axis is in the vertical direction up,
 *  \li Z-axis is along the beam line in the downstream direction.
 */

/** \page local_coordinate_system local coordinate system
 *
 *  The local coordinate system of the MC simulation is normally defined as follows:
 *  \li X-axis is along the longest detector edge in the non-dispersive direction beam-left for octant 3,
 *  \li Y-axis is along the shortest detector edge in the dispersive direction away from the beam line,
 *  \li Z-axis is perpendicular to the detector plane in the downstream direction.

 *  A complete list of Lund particle type codes is summarized in the PDG: http://pdg.lbl.gov/2011/reviews/rpp2011-rev-monte-carlo-numbering.pdf

 *  The most important particle codes are:
 *  \li electron: 11
