This class describes the digitisation scheme for a sensor of the GEM. The sensor shape is circulare with inner and outer radius. The sensor center is defined in 3-D space. The rotation angle is defined as angle around the beam axis. In the sensor two views of strip orientation are defined by specifing the angle of rotation and the smallest pitch. The strip rotation angle should be understood as follows:

• rotation angle 0 - radial strips
• rotation angle 90 - concentric strips
• rotation angle 60 - tilted radial strips by angle of 60deg at inner radius, the strips are straight, which means that the angle between the tilted strips and radial strips reduces as the radius grows
• rotation angle -60 - same as above, but the start angle is -60deg The strip pitch for concentric strips is the strip width. The strip pitch for radial and tilted strips is defined as the distance between strip borders at the inner radius.
