/** CbmStsSensorDigiPar.h
 *@author V.Friese <v.friese@gsi.de>
 **
 ** Parameter container for the digitisation of a sensor of a STS
 ** strip station.
 ** Supports the following digitisation types:
 ** 1 = hybrid pixel
 ** 2 = strip, readout of all strips
 ** 3 = strip, readout at bottom corner, double metal layer
 ** Coordinates and rot. angle are in the global coordinate system. 
 ** In the internal coordinate system, x is across the front side strips
 ** and y along the front side strips. Irrelevant for pixel detectors.
 ** Angles are stored and accessed in radians, but must be given in
 ** degrees in the constructor.
