 theXChannelBoundaries positions are the x low limits for each channel (EM section)
 theZHadChannelBoundaries are the z low limits for each HAD channel at y = 0 position
 the coordinates are given with respect to the center of the enclosing volume
 as defined in the geometry: X0,Z0,Y0
 tiltangle is the 45 deg angle of the plates
 dXEMPlate, dXHADPlate is the half width of EM, HAD plates
 dYEMPlate, dyHADPlate  is half height (DY/2) of the EM, HAD sections
 dXAll is the half width (DX/2) of all sections	
 all dimmensions are in mm and rads
