\section{Coordinate Systems}

The ALICE coordinate system is defined as, Z along the beam counter clock wise
direction, X towards the center of the LHC, and Y set so that it is a right
handed coordinate system (up). This is illustrated in
Figure~\ref{ITSMan:ch2:ALICEcoordinateSystem1}. The $[0,0,0]$ of this
coordinate system is defined to be the center of the expected interaction
diamond. This is the point about which all of the ALICE detectors will be 
built. In figure~\ref{ITSMan:ch2:ALICEcoordianteSystem2} is shown this same
coordinate system on the scale of the ALICE detector.
