The chambers have either a rectangular or a trapezoidal shape to first approximation.

The former is mounted in the barrel while the latter can be found on the middle and outer big wheels. In Run 1 & Run 2, the inner wheel also consistet of MDT chambers. The local coordinate system is placed in the center of the chamber and the x-axis is parallel to the long & short edges of the trapezoid as illustrated in https://gitlab.cern.ch/atlas/athena/-/blob/master/docs/images/TrapezoidalBounds.gif For the rectengular barrel chambers, the X length is read from longHalfX
